inet_aton 见 Socket 模块文档
unpack 见 perldoc -f pack
QUOTE:
inet_aton HOSTNAME
Takes a string giving the name of a host, and translates that to an opaque string (if programming in C, struct in_addr). Takes arguments of both the 'rtfm.mit.edu' type and '18.181.0.24'. If the host name cannot be resolved, returns undef. For multi-homed hosts (hosts with more than one address), the first address found is returned.
