Aggregation for IPv4-compatible IPv6 address space
Hi all: With IPv4-compatible IPv6 address space, could I aggregate the address space? say 192.168.0.0/16 become ::192.168/112? or It must be converted to native IPv6 address space? Just wondering, Get the name you always wanted with the new y7mail email address. www.yahoo7.com.au/y7mail
Re: IPv6 questions
It does make sense though. Say one megabits interface with 20 VLANs. In that scenario, every VLAN, usually has own link-local address. It is more practical than multiple interfaces with same link-local address. I found this on Juniper router and now assume it is Juniper specific implementation.

I have never seen/heard of an RFC for it either and would certainly wonder WHY?. :) Scott -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Erik Nordmark Sent: Tuesday, January 29, 2008 1:44 PM To: snort bsd Cc: nanog@merit.edu; juniper-nsp Subject: Re: IPv6 questions snort bsd wrote: Never mind it is the VLAN number. But which RFC define this? I've never seen an IPv6 RFC specify to put the VLAN number in the link-local address. Thus this must be an (odd) choice made by some implementation. Perhaps the implementation somehow requires that all the link-local addresses for all its (sub)interfaces be unique, even though the RFCs assume that the implementation should be able to deal with multiple interfaces with same same link-local address.

How does the VLAN tags affect the conversion? With the rule of FF FE stuffing, I can see clearly work on the ptp interfaces. But on those Ethernet based VLANs, it doesn't seem to follow that pattern: Current address: 00:90:69:4a:b9:5d, Hardware address: 00:90:69:4a:b9:5d well, i assume the link-local should be fe80::290:69ff:fe4a:b95d/64. actually, it shows: Destination: fe80::/64, Local: fe80::290:6903:94a:b95d how does the router get this 03 09 instead of ff fe?

dns for private domain
Hi All: Does a DNS have specific reqirements? I imagine it would not need the root cache file since it would go nowhere except own domain. I set up a DNS (named it as lab.com) server in the lab and it seems to be working fine; I can resolve hostnames on my linux box and window box, but on Sun Solaris machine I got non-exist domain error. Anything specific for the Solaris' resolver or I need to do some extra on my DNS configuration? TIA Dave Find local movie times and trailers on Yahoo! Movies. http://au.movies.yahoo.com
