> The first appearance of reversed DNS strings predated the Internet domain name standards. The UK Joint Academic Networking Team (JANET) used this order in its Name Registration Scheme, before the Internet domain name standard was established. For example, the name `uk.ac.bris.pys.as` was interpreted as a host named `as` within the UK (top level domain .uk)
But I don’t know if uk.co.somethingsomething did or did not exist at that time. Or if it was only introduced after the Internet domain name standards we use today existed and so was .co.uk from the beginning.
