I've switched the AMPR.Org and 44.in-addr master nameserver over to using a new database and maintenance software. All seems to be working correctly.
If you encounter any problems looking up a hostname or IP address in the relevant ranges, please let me know.
There is a change in the content of the downloadable zone file ampr.org.gz
This causes problems in my scripts. I can modify the scripts, but first let's see if you can make them like before so similar issues for others could be avoided...
