Currently we are doing approximately what other ping implementations are doing:

ping -s 1 localhost

linux:
PING localhost (127.0.0.1) 1(29) bytes of data.
9 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64

macosx
PING localhost (127.0.0.1): 1 data bytes
9 bytes from 127.0.0.1: icmp_seq=0 ttl=64

netbsd-old
PING localhost (127.0.0.1): 1 data bytes
[no response]

netbsd-current
PING localhost (127.0.0.1): 1 data bytes
8 bytes from 127.0.0.1: icmp_seq=0 ttl=255

We can change it anyway we want...
