WebSep 24, 2014 · Limit on hops in IPv4 and IPv6. I was reading IPv4, and in it it specifies time to live, aka TTL or "max hops" in IPv6 since this is what it really represents. My concern is that this value is 8 bits, thus has a max value of 255, which is decremented at each "hop" through a Gateway. That means that any two points in any network using IPv4 have ... WebGreg is right, TTL (or better expressed as "hops to live" as IPv6 header states it more precise) does not care about AS-boundaries.
