Do you want to solve
6to4 with perl?
# take IP4 address string
my $IP_str = '192.0.2.4';
# convert the numbers to hex
my @IP4_a = map { sprintf("%02x", $_) } split(/\./,$IP_str);
# embed these hex numbers in the IPv6 template
my $R = sprintf("2002:%s%s:%s%s::/48", @IP4_a);
# output the result
die "($R)";
something like that?
sub ipv4_6to4{
return sprintf("2002:%s%s:%s%s::/48", map {sprintf("%02x",$_)} split
+(/\./,$_[0]));
}
