As I recall, the world didn't end when the NSFNET NSSs were installed and they decremented TTL twice.
The world didn't end but I have a vague, cobwebby recollection of having to patch our BSD kernels to use a greater TTL. One of the nice things going on in the IETF right now is that people are rethinking many of their assumptions about what goes without saying. For example, in order for TTL to be effective, not every node needs to decrement it -- we just need to be sure that no loops can form where it doesn't get decremented. Similarly, traceroute was a hack from day one (although a clever one, and over time it even became elegant). If you want to know underlying hops for a particular subnet, use a tool for that subnet type -- you don't need to make everything respond to traceroute. See you ... Scott
