gettable uses flat files to map name= s to numbers.=C2=A0 It hasn't existed in probably 30+ years, and I can&= #39;t even imagine how large the files it creates would be for the modern i= nternet.

Amusingly, for some strange reason it sti= ll exists in Solaris 11.2: https://docs.oracle.com/cd/= E36784_01/html/E36871/gettable-1m.html

A quick search found me a site with an arc= hive of the HOSTS.TXT files that gettable and friends used: https://emaillab.jp/dns/hosts/
