Your example sorts lexically, not numerically. It'll sort 10.10.10.10 before 10.10.10.2, for example:

my @lines=<DATA>;
print sort @lines;
__DATA__
10.194.196.9  made-up
10.194.196.55 heckyll
10.194.196.57 txwl013w
10.194.196.61 krios
10.194.196.62 stasis # dial up server

This sorts the "made-up" line to the end, whereas the original poster presumably would want it first.

Like the other replies said, a numerical sort is more appropriate here. The number of "cycles" used either way is going to be pretty trivial.
