3fff:BAD:: Seriously though, I remember playing little games like this numbering Novell IPX network segments back in the 1990's. After IP came on the network I think I was accussed of polluting pristine IPX nets....then... I'll stop now. ;-) wfms

:-D Thanks. I wonder about 2001:db8 The person who made it up must like the movie "2001: a space odyssey" and Aston Martin. Even though I don't think they ever made a db8, but they made or make db2, db4, db5, db6, db7 and db9 amongst others.

For IPv6 I consider it "address spam". My content filter will give you some extra tiny score if your MX uses such an address. If you want to do it, make sure you do understand the restrictions that apply to IPv6 addresses, like U/G bits, etc. Too many people unfortunately just think it's cool in a weird geeky sense and violate RFCs with them. I was very close to write an article about that after W6D... /bz -- Bjoern A. Zeeb You have to have visions! Stop bit received. Insert coin for new address family.

Perhaps I missed something in an RFC somewhere, but I believe those bits only have meaning locally on an Ethernet LAN. They have no meaning when used on non-Ethernet networks, for instance POS or on a Loopback. If someone wanted to use them for a /128 virtual for their web site for instance that would be ok. Or, turning that around, if you assume an IPv6 address is part of a /64 on an Ethernet network, you have made a false assumption. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/

A load-balancer attached to it's first hop router via a /126 may well advertise the virtual ip's it's serving (and treat them) as /128s. the assumption that links are /64s falls down a lot (even on ethernet) when most of them are point-to-point.
