Hi Mario,

Probably neither. It depends who you ping--maybe you're trying to reach a
different host than you were with your last tests. BSD still sets the ttl
to 255, I think, but if anything changed, perhaps FreeBSD has changed this
default, but it's not in ping(8).

Ping localhost and observe. Other systems may set it to different values.
Some just don't change it--in this case you may see something "near" 255,
depending on the amount of hops.

The ttl values you see on a ping are taken from the return packet, so
ping(8) itself has precious little to do with it.
