Considering the large chunk of 24/8 they have, I can't imagine why they had to use RFC 1918 addresses throughout their infrastructure. When I raised issues about this (just after getting a T1 to their network), they had no answers other than that since they chose an MTU of 1500 bytes for all their links, they didn't think path MTU discovery would be an issue.
well then, they're obviously clueless.
Hasn't this come up here before? I'm too lazy to go check the archive, but I seem to remember a discussion of this topic. IIRC, the reason/excuse given (lame or not) was that they use equipment that does not deal well/at all with CIDR or VLSM or somesuch. Or am I thinking of someone else? Not that I recall it being a widely accepted reason here. :-) --Jeff ObRandy: Cynical response regarding people simply complaining about that which they do not fully understand omitted.
