OK, it works very well, but is there a way which is common to IPv4 and
IPv6 to get ICMP packets?
Obtaining addresses is common to both protocols, but now I get IP header +
ICMP header from IPv4 sockets, and ICMP header from IPv6 sockets, so I
must process them differently (basic ICMP packets have the same structure,
only different values so routines for ICMP could be universal).
You wrote that there is no portable way to obtain IPv6 + ICMPv6, so is
there a way to portable obtain only ICMPv4 (without IPv4 header)?

With regards
