Re^2: Sorting log files with IP addresses (duplicates)

From the inet_aton docs:

For portability do not assume that the result of inet_aton()
is 32 bits wide, in other words, that it would contain only
the IPv4 address in network order.

Using pack is probably a better option:

my $ip = pack(C4 => split /\./, $src);

True, it depends on the characteristics of inet_aton(3) however using pack() and split() only works if the IP address is in the dotted quad format while inet_aton() will work with any valid IP address and return undef if the address is not valid.	[reply]
