WebmasterWorld mirrored by Cornell?

[Pfui]

I just encountered two curious URLs while searching G:

Blocking the Java UA
[webmasterworld.com.honeycomb.cs.cornell.edu:8888...]

Apache Web Server
[webmasterworld.com.honeycomb.cs.cornell.edu:8888...]

Huh-wha? .honeycomb.cs.cornell.edu:8888?

Thing is, those URLs dead-end, whereas the 'originals' (sans cornell) still exist:

Blocking the Java UA [webmasterworld.com]

Apache Web Server [webmasterworld.com]

Next time I happen to spot a WebmasterWorld/Cornell Computer Science URL (or one via webrover.de or anywhere else), should I -- ignore it? Bug-report it?
