IPv6 scares the bejesus out of me. I don't know a whole lot about it yet, but it looks like a completely different animal. It'll be a whole new world - all the routing protocols I know and love are being revised for this. IS-IS is the only protocol right now that supports it. 128 bit long address..written as 8 16-bit pieces. Tell me this doesn't look intimidating... FEDC:BA98:7654:3210:FEDC:BA98:7654:3210 And then there's the prefix-length... Ugh.
