Hello,

Actually, looking at the code I've observed some weird behavior :  for 
example to fix the force_send_socket IPv6 address, a call to str2ip6() 
(from resolve.h) is done (via resolvehost()). The function tries to 
manually parse the IP address, so it makes me wonder why not use a 
library function like inet_pton(AF_INET6... to get the correct structure.

A possible bug is that with the current code, IPv4 mapped to IPv6 
(x:x:x:x:x:x:d.d.d.d) will not be parsed correctly.

Why don't we use inet_pton(AF_INET6 ... . Any reasons?

Cheers
Marius
