during analyzing my webserver logfiles I've realized, that one ipv6logconv
run requires more than 20 min per. This was the start for profiling this
tool and implement a major speed improvment.

2 changes were made:

a) ipv6logconv:
     - implement a lookup cache for speed-up
        saved around 50% before implenting b)
        saves around 20% after implementing b)

b) lib/libipv4addr
     - add a hint table for speed-up IPv4 registry lookups
        speed up by 10 times!

New version is now in CVS, if no problems would be reported, I will publish
version 0.49 next weekend.

For those who didn't know what ipv6logconv can do for you, take a look at
the statistics pages on

Hope this helps,
