Here's another option that will generate your desired results:

use Modern::Perl; use Sort::Key::IPv4 qw(ipv4sort); my %hash; do { chomp( my ( $ip, $fld2, $fld3 ) = ( split /\t/ )[ 1 .. 3 ] ); push @{ $hash{$ip} }, "$fld2=$fld3"; } for <DATA>; print "$_|" . join( '|', @{ $hash{$_} } ) . "\n\n" for ipv4sort keys % +hash; __DATA__ 9885 10.10.9.48 Room 1105A 9885 10.10.9.48 Jack 1105A--05D 9885 10.10.9.48 org_code B703 9885 10.10.9.48 Building 1268A 114948 10.10.184.0 nasa_nets off 114948 10.10.184.0 blockSecName test name 114948 10.10.184.0 blockTechName brian test 114948 10.10.184.0 blockAdminName test admin 114949 10.10.184.0 blockSecName John G.

Output:

Update:

I've added the Sort::Key::IPv4 module to use its ipv4sort on the IP4 addresses in your data set. The advantage is an ordered list of results. Its limitation is not sorting on IP6 addresses. This IP4 sorting was easily added, and can be easily removed if not needed.
