Yeah, IP addresses not implemented, but actually it's not too hard to add support for them. This is a patch for Sniffer/HTTP.pm, it's just a simple hack, it's not well tested, and actually there's some issues here, but it should work in most cases:

And here's the example of how to get IP addresses in callbacks:

use strict;
use warnings;
use Sniffer::HTTP;

my $VERBOSE = 0;
my $debug   = 0;
my $sniffer = Sniffer::HTTP->new(
    callbacks => {
        request => sub {
            my ( $req, $conn ) = @_;
            my $src   = $conn->tcp_connection->src_host;
            my $sport = $conn->tcp_connection->src_port;
            my $dst   = $conn->tcp_connection->dest_host;
            my $dport = $conn->tcp_connection->dest_port;
            print "Request: $src:$sport -> $dst:$dport\n";
        },
        response => sub { my ( $res, $req, $conn ) = @_; },
        log     => sub { print $_[0] if $VERBOSE },
        tcp_log => sub { print $_[0] if $VERBOSE > 1 },

    },
    timeout => 5 * 60,    # seconds after which a connection is consid
+ered stale
    stale_connection => sub {
        my ( $s, $conn, $key );

        if ($key) {
            print "Connection stalled .... $key ....\n" if $debug;
            $s->log->("Connection $key is stale.");
            $s->remove_connection($key);
        }

    },
);

$sniffer->run('wlan0');
