Old Internet Files

Every so often, I have a desire to see old (1990s era) Internet files. Lists of domains, root servers, and so forth. If you are good with search engines, you can find a few. But that's it.

So I hunted and hunted, found what I could, and put them online here. Note that they cannot be guaranteed to be accuarate; it is likely that at least a few were modified 'back in the day' for then-useful purposes. And it is also possible (although unlikely) that someone could have modified some of the files for more nefarious purposes.

UPDATE: There's a similar page at https://emaillab.jp/dns/hosts/. There are a number of files there that are not here, and vice versa, so please check it out.

hosts.txt

The hosts.txt file lists networks and hosts, and was originally the primary way of finding the IP addresses of hosts on the Internet.

domain-info.txt

According to RFC 1032, the domain-info.txt file "contains a concise list of all top-level and second-level domain names registered with the NIC and is updated monthly."

It is a list of all known domains, although mostly covers the gTLDs (listing ccTLDs as 'No known domains under this top level domain'). It starts with a line "DDN NIC DOMAIN SUMMARY" followed by the date.

Domain Files

These files list all the sub-domains for a TLD, without their nameservers, usually including the organization that owns the domains.

I have omitted .gov and .mil, as these appear to have been removed from search engines. I don't see the harm in nearly 20-year-old zone files, but want to be respectful. And no, those files aren't on this server.

Zone Files

These files list all the sub-domains for a TLD, as well as their nameservers

Here are some that were once freely available. Note that I cannot add zone files that are properly protected (e.g. require signing a zone file access agreement that prohibits publication, as is usually the case now).

I have omitted .gov and .mil, as these appear to have been removed from search engines. I don't see the harm in nearly 20-year-old zone files, but want to be respectful. And no, those files aren't on this server.

asn.txt (ASNs - Autonomous System Numbers)

These files list the organization for each Autonomous System (essentially, a group of IPs that all have the same routing policy -- for example, an ISP would normally have its own AS).

This file contains a list of autonomous system numbers and names of all
registered ASNs.  The column on the right below contains the NIC

information may be obtained about any of the ASN coodinators in this
list querying the InterNIC WHOIS server.  For questions or updates on this
information please contact the InterNIC Registration Services Hostmaster staff,
