The only problem with compatibility - is compatibility with which version.

IPv4 as default is compatible with all official versions including 0.99.

IPv* as default is compatible with the unofficial (but head for 9 months) version 0.99.6.1

my @a=qw(random brilliant braindead); print $a[rand(@a)];

In reply to Re^2: What should be default for Net::Server - IPv4, IPv6 or IPv* by Rhandom
