Re: Companies using public IP space owned by others for internal routing
I had a vendor at $dayjob prior to my arrival who assigned all their customers ip space based on the customer number. when i got there all the internal network was assigned space from an company in the middle east. $dayjob didn't have the in-house knowledge to know what was going on and as they never worried about the middle east it didn't affect their business.

One reason our vendor does this is to not get on black hole/spam lists or to cause their ISP issues, as well as having proof that they are allowed to send specific traffic to specific addresses for a specific time period. The test managers then know what to expect and to head off abuse notifications after detection of the specific traffic. We, also, use this traffic to test other vendors we might have and only after detection we will have white lists or black lists put in place as warranted. I would expect the company in question to be able to provide documentation that could track any specific traffic back to an engagement that has the approval of their customer. If they have been around for a bit they should have a track record and may have current IP space that could be vetted to see what condition it is in. Are they leaving it or adding too it. If they are leaving their current space then find out why. James

Re: IPv6 Deployment for Mobile Subscribers
Ricardo, I know from previous discussions on this list that Android phones are looking for DHCPD leases and not /128's or /64's. From what I remember this is due to the current requirement for multiple ipv6 subnets for various applications (vpns among others) to function correctly. As a result Google has disabled Android from receiving a DHCP lease as it wasn't long enough. if you look back about 6 months there is probably 100+ posts on the subject.

The office is taking full BGP routes from tier 1 providers using a Juniper MX80. They are establishing their first branch location, and need the branch location to be able to securely communicate back to headquarters, AND be able to use a /24 of headquarters public IP addresses. Ideally the device at the HQ location would hand out public IP address using DHCP to the other side of the tunnel at the branch location. We know that in an ideal world it would be wise to get layer 2 transport connections from HQ to the branch location, but lets assume that is not an option. Please don't flood this thread about how it could be an option because it's not at this time. This setup will be temporary and in service for the next year until we get fiber to the branch site. Let's assume at the branch location we can get a DOCSIS cable internet connection from a incumbent cable provider such as Comcast, and that provider will give us a couple static IP address. Assume as a backup, we have a PPPoE DSL connection from the ILEC such as Verizon who gives us a dynamic IP address. What solution could we put at the HQ site and the branch site to achieve this? Ideally we would want the solution to load balance between the connections based on the connections speeds, and failover if one is down. The cable connection will be much faster speed (probably 150Mbps down and 10 Upload) compared to the DSL connection (10 download and 1 upload). If we need more speed we can upgrade the cable modem to a higher package, but for DSL that is the max speed so we might have to get multiple DSL lines. The cable solution could always be used as the primary, and the DSL connection could only be used as backup if that makes things easier. If you were to do this with Juniper or Cisco gear what would you have at each location? What technology would you use? Colton, The Cisco solution for this would be Cisco Intelligent WAN (iWAN) utilizing ASRs and ISRs. iWAN utilizes a combination of DMVPNs and pFR to make this happen. Another name I've heard but have no feedback on is Viptela I know there is Pepewave and a couple of other software solutions that seem to have a proprietary load balancing solutions developed, but I would prefer to use a common Cisco or Juniper solution if one exists. There will be 50 users at the branch office. There is only one branch location at this time, but they might expand to a couple more but under 10. James

Another possible option (although costly) is installing a Ruckus device at each location; we have a Ruckus infrastructure at our HDQ and it works great (almost too good, it's super sensitive) at picking up rogues.

If your IP range is 0.0.0.0 - 191.255.255.255 you are not affected (by this particular bug) by using .0 or .255 as the last octet unless the address is ALSO the last octet of the classful boundary for your subnet. In effect, these OS's simply enforce classful boundaries regardless of the subnet mask you have set. As the KB states, this bug affects supernets only. I'm not trying to defend MS (they can do that themselves), but your statement was misleading. I can distinctly remember having the issue in 10/8 address space with Win2k and WinXP We do, sometimes, use .0 and .255 addresses. Most clients work fine with them (including XP). However, I have personally seen a few networks where an administrator had blocked .0 and .255 addresses, causing problems for people on his network communicating to hosts that ended in .0 or .255. It has been years since I have seen an issue with a .0 or a .255 IP however. Given fears over IP shortages, even a couple percent of addresses wasted due to subnetting can be cause for adjusting network policy. I would not be surprised if folks who excluded .0 and .255 addresses from their assignable pools will re-evaluate that decision over the next few years. --Blake

Te prefix(es) to be advertised. Of these 5, only items 2 and 5 have to come from the customer and the customer needs to provide both of these to both ISPs anyway for them to configure their side. It would be trivial for providers and CPE vendors to develop a standardized API by which a router could retrieve all 5 pieces of information for a given connection once that connection is plugged in to the router. It could literally be as simple as: 1. Port gets address via SLAAC or DHCP 2. Port retrieves XML configuration document from http://bgpconfig.local (or user-specified URL provided by ISP, or whatever) XML PROVIDERASN6939/PROVIDERASN LOCALASN65512/LOCALASN PROVIDERIPv4192.0.2.21/30/PROVIDERIPv4 PROVIDERIPv62001:db8:1fea:93a9::1/64/PROVIDERIPv6 LOCALIPv4192.0.2.22/30/LOCALIPv4 LOCALIPv62001:db8:1fea:93a9::2/64/LOCALIPv6 PrefixInformation PrefixAccepted203.0.113.0/24/PrefixAccepted PrefixAccepted198.51.100.0/24/PrefixAccepted PrefixAnnounced0.0.0.0/0/PrefixAnnounced /PrefixInformation /XML (Yes, I realize that is a bit of an oversimplification of the XML syntax, but you get the idea) 3. Router configures port and BGP session according to received XML document, including appropriate prefix filters. 4. Router runs with that XML based configuration as long as link-state and power remain. That would allow a zeroconf BGP-enabled router in relatively small hardware accepting a default route that would work at least as well as today's dual-NAT based boxes. Note that BGP is not redesigned or even altered to achieve this. Since Linksys/DLink/Netgear/$EVERYONE already has web servers and clients embedded in their gear, the XML parser (or JSON or whatever they choose to use for standard encoding) would be pretty straight forward. From a SMB perspective this is part of the problem. Why pay for: 1. An ASN 2. 2 BGP connections 3. PI space 4. More expensive hardware (potentially and probably) when I'm only going to get a Default Route? I've added complexity to my life, administrative and OPEX overhead when I'm getting no benefits of BGP other than a default route. I can get a default route from a provider without adding complexity and overhead. An SMB who does not have a staff on hand wants it cheap and to work. Everything else is a potential expense they don't want to spend. They don't want to have to call either their support company or vendor because the Internet is down, at most they want to pull the power on the router and plug it back in and have it all work. At best they want to only know what that little black box with the blinky lights is when someone packs it into a box because it's wasting power and now the Internet is broken. From an SMB who has a staff on hand it still may not be worth it if they don't have someone who is BGP smart. And truth to tell *you* don't want more BGP idiots polluting the routing table either intentionally or unintentionally. Conversely if you do make BGP that available to SMB's and home users (not necessarily a bad thing) the issues with routing table size has to be dealt with. Right now there are roughly 42K ASes with routes in the routing table. Add SMB's and home users and your looking at potentially millions of ASes with routes in the routing table. Heck if you *only* double the ASes and associated routes many many routers are going to crash and need replacement. Yes, the operator/provider has to do some additional configuration, but speaking as a network operator, I know that this can be automated because the management of BGP configurations, including the filters _IS_ that automated where I work. If the provider is telling the router which prefixes to permit announcement of through the configuration URL, then it's even more reliable, right?

Re: IPv6 end user addressing
It isn't hard to do some arithmetic and guess that if every household in the world had IPv6 connectivity from a relatively low-density service like the above example, we would still only burn through about 3% of the IPv6 address space on end-users (nothing said about server farms, etc. here) but what does bother me is that the typical end-user today has one, single IP address; and now we will be issuing them 2^16 subnets; yet it is not too hard to imagine a future where the global IPv6 address pool becomes constrained due to service-provider inefficiency. what is the life expectancy of IPv6? It won't live forever and we can't reasonably expect it too. I understand we don't want run out of addresses in the next 10-40 years but what about 100? 200? 300? We will run out and our decedents will go through re-numbering again. The question becomes what is the life expectancy of IPv6 and does the allocation plan make a reasonable attempt to run out of addresses around the end of the expected life of IPv6.

Re: dynamic or static IPv6 prefixes to residential customers
I don't understand why this is a problem if your ISP gives you a static address. There are, of course, other sources of addresses available as well. Nobody has yet presented me a situation where I would prefer to use ULA over GUA. while link-local is necessary it's also probably not sufficient. t True. Owen Lets look at some issues here. 1) it's unlikely that a normal household with 2.5 kids and a dog/cat will be able to qualify for their own end user assignment from ARIN. 2) if their router goes down they loose network connectivity on the same subnet due to loosing their ISP assigned prefix. 3) If they are getting dynamic IP's from their ISP and it changes they may or may not be able to print, connect to a share, things like that. these 3 items make a case for everybody having a ULA. however while many of the technical bent will be able to manage multiple addresses I know how much tech support I'll be providing my parents with either an IP address that goes away/changes or multiple IP addresses. I'll set them up on a ULA so there is consistency. Complain about NAT all you want but NAT + RFC 1918 addressing in IPv4 made things such as these much nicer in a home and business setting. james

Interesting... I have a normal household. I lack 2.5 kids and have no dog or cat. I have my own ARIN assignment. Are you saying that the 2.5 kids and the dog/cat would disqualify them? I can't find such a statement in ARIN policy. Are you saying that a household that multihomes is abnormal? Perhaps today, but, not necessarily so in the future. Yes I am saying a household that mulithomes is abnormal and with today's and contracted monopolies I expect that to continue. You are not a normal household in that 1) you multihome 2) you are willing to pay $1500+ US a year for your own AS, IP assignments while I don't disagree with the assertion that this is unrealistic the annual fee is $100 per org-id for direct assignments. sorry was unclear - I was guessing $1500+ for ASnumer + IP Assignments but not counting ISP costs for a year. Looks like ARIN is charging about $1250 per year for a new IPv6 assignment and the AS yearly cost is rolled into that. Granted ISP costs will probably be in the ballpark of $150 per month for 2 consumer grade connections and more for business or better connections. James
Re: dynamic or static IPv6 prefixes to residential customers
I would argue that I am not an abnormal household by any definition other than my internet access and that even by that definition, I am not particularly abnormal where I live. your based out of san jose, there might not be any other area like that in the U.S. as far as connectivity and concentration of i.t. savy. there might be 10 cities in the U.S. with the same infrastructure and availability as you have accessible. there are not 50. while not abnormal where you live, it is abnormal to the rest of the country. There are many people I know of with much more expensive and elaborate internet connectivity to their houses than what I have within 30 miles of me. While I don't think I represent the typical residential ISP customer, I do think that the typical customer will eventually learn what static addressing is and will want it for a variety of reasons. Owen scott's user base is more typical than what you can find in your neighborhood. i am sure some of the same users live within 30 miles of you too but you,i, scott, or anybody else on this list can not be considered normal in this respect. james
