Looks like haukex may have solved your problem above, so just an observation:

• It's 2017, we really should be using address family independent Socket routines.

Unless you're *guaranteed* that:

• @ips will only be IPv4 addresses, or
• you're on a Perl older than 5.14, or
• your Socket module version is older than 1.94, or
• you're using an operating system circa Windows XP ...

you may encounter IPv6. So planning for it is easy:

#!perl
use strict;
use warnings;

my @bla = qw ( 34.230.53.172 2607:f8b0:400d:c0b::63 );
for my $bla (@bla) {

### What you need below ###
use Socket qw( AF_INET IPPROTO_TCP );

my $AF_UNSPEC   = eval { Socket::AF_UNSPEC() };
my $NI_NAMEREQD = eval { Socket::NI_NAMEREQD() };

my %hints = (
    family   => $AF_UNSPEC,
    protocol => IPPROTO_TCP
);
my ( $err, @getaddr ) = Socket::getaddrinfo( $bla, undef, \%hints );
for my $addr (@getaddr) {
    my ( $err, $host, $service )
      = Socket::getnameinfo( $addr->{addr}, $NI_NAMEREQD );
    printf "%s\n", ( defined($host) ) ? $host : $err;
}
