You could use inet_aton() from Socket to transform the IP into a sortable string.

use strict;
use warnings;

use 5.014;
use Socket;

my %hosts = (
   host0 => { ip => q{17.198.26.3} },
   host1 => { ip => q{113.34.87.9} },
   host2 => { ip => q{23.6.8.136} },
   host3 => { ip => q{10.45.18.207} },
   host4 => { ip => q{192.168.31.8} },
   host5 => { ip => q{10.17.227.3} },
   host6 => { ip => q{192.168.1.6} },
   host7 => { ip => q{172.16.1.1} },
   host8 => { ip => q{3.77.45.22} },
   host9 => { ip => q{17.216.1.1} },
   );

say qq{$_ - $hosts{ $_ }->{ ip }} for
   map  { $_->[ 0 ] }
   sort { $a->[ 1 ] cmp $b->[ 1 ] }
   map  { [ $_, inet_aton($hosts{ $_ }->{ ip } ) ] }
   keys %hosts;

The output.

host8 - 3.77.45.22
host5 - 10.17.227.3
host3 - 10.45.18.207
host0 - 17.198.26.3
host9 - 17.216.1.1
host2 - 23.6.8.136
host1 - 113.34.87.9
host7 - 172.16.1.1
host6 - 192.168.1.6
host4 - 192.168.31.8

I hope this is helpful.
