Various ways using various mysteriously named functions from various mysteriously named packages, but it's easy enough with pure perl:

## Subs to convert dotted-quads to integers and vice versa
sub dq2n{ unpack 'N', pack 'C4', split '\.', $_[ 0 ] };;
sub n2dq{ join '.', unpack 'C4', pack 'N', $_[ 0 ] };;

$start = dq2n( '71.100.100.180' );;

print n2dq( $_ ) for $start .. $start + 100;;
71.100.100.180
