Re: do ISPs keep track of end-user IP changes within thier network?
been a while, but seems like lately it's more a question of how long. ISPs can be in position where they need to, but as things have consolidated, seems like they'd really like to forget it as soon as they can. If you've got a specific case in mind, likely best to find a direct contact and get a response about policy, even if it has to be off-record.

Re: do ISPs keep track of end-user IP changes within thier network?
While I'm also not an attorney, my reading of 18 USC 2703 leads me to believe that records need only to be preserved for 180 days if a governmental entity (i.e. law enforcement agency, regulatory body, prosecutors office, etc) makes a request that such records be preserved. To the best of my knowledge, there's no statue on the books (at least at a federal level) which would mandate that a provider keep any records relating to dynamic IP allocations. -- Regards, Jake Mertel Nobis Technology Group, LLC *Web: *http://www.nobistech.net *Phone: *1-480-212-1710 *Mail:* 6930 East Chauncey Lane, Suite 150, Phoenix, AZ 85054 On Thu, Dec 12, 2013 at 9:07 AM, R.

Re: CNAME issue
short answer: can't be done You cannot have a cname and 'other' information for same entry. As a zone requires an SOA record, you cannot have a CNAME for the entire domain (theoretically a registrar could do it in .com, but afaik nobody does his). Depending on customer's requirements, can put in a wildcard *.abcd.com in cname xyz.com Or can load the same zone file for both abcd.com and xyz.com, so in both, maildomain goes to the same place On Wed, 11 Dec 2013, Methsri Wickramarathna wrote: Hi All, One of our customer having the following requirement.

CWDM question
Hi. We are doing a fiber link between us and another SP using CWDM. There is traffic flowing just fine at the 1310 wave, and have recently added a 1471 wave. On the 1471 wave there are some problems with it. From our perspective, and we have packet captured this, we are transmitting data to them, but they say they are not seeing anything. We are receiving from them, and while we show that packets are leaving our interface to them, they are getting nothing at all. There are good light levels between the two locations and do not understand why they are not seeing traffic from us even though we are sending it. Our packet counters show we are transmitting to them and receiving from them. Is it possible to have RX and TX light and things appear to be ok, but have the RX on their side fubar in some way that it is not operating correctly in that our traffic is not reaching them? Thanks.

Light levels on our side are good and within spec. I have been trying to find out from the SP what theirs are at presently, but when the circuit was first lit levels were taken and found to be within spec on both ends. Only 1310 and 1471 in use. We are 800+km away from the site so its hard to get some hands/eyes there at present. Thanks.
Re: CWDM question
That is whats next. They took down the whole fiber instead of just the 1471 wave to test which killed transit...grrr.. They say their tx/rx are within spec. Next is jumpers and sfp swaps I guess.

Maybe it is a bad jumper or port on the 1471 receive on their end or send on your end. If the two switches can be brought to the same location, you might also want to connect them together using short jumpers, but make sure you have a power meter to ensure you use the proper attenuators to avoid burning out your optics.
