[H-GEN] Slow telnet and ftp ??

[David Shackleton]

Is there a simple way to disable the reverse lookups for a whole subnet,
without disabling idents completely?

I don't want our gateway to know the hostnames, and thus none are defined,
but this is (unsurprisingly) causing delays whilst the lookup times out.

(...and I'd rather block the whole subnet than declare dummy entries for
each and every possible address). 

Thoughts?
