I wouldn't be sure about that.

There are IPs. '::1' is the IPv6 IP for 'localhost', to which this
hostname resolves first on a SuSE 8.0 (and if that fails, it resolves
to '127.0.0.1').
Which means that it's very likely that this request came from one of
your applications.

Try 'telnet localhost 80' and then enter 'CONNECT :::2121
HTTP/1.1\n\n', it should reproduce the log entries.
If those log entries become annoying, just comment out the IPv6 IPs
form /etc/hosts and they should disappear.

Maybe the Apache isn't capable of IPv6 IP addresses (don't guess so)
or the client which issued the request has sent a malformed request.
