I have sort-of resurrected the bitnet zone file.
SInce bitnet is not an official TLD you will need to specify the nameserver, since the
root won’t forward it.
So, grab a copy with:
dig IN AXFR bitnet @ns.fsf.net
Note that the old zone file had underscores in the hostnames. Anywhere you see a dash
here, it should be an underscore to be the correct bitnet name.
bit.net <http://bit.net/> is still alive (from the IP address it’s still a machine
at Princeton) serving a document explaining the bitnet history.
