Tld.subdomain.name.subname
Way back in the early dawn of the 'net, there were two competing notations for specifying a FQDN, the familiar name.subdomain.domain.tld (such as news.bbc.co.uk) and the reversed tld.domain.subdomain.name (uk.co.bbc.news). And if memory serves, only the UK used the latter style of FQDN for a period of time. Nowadays, the reversed FQDN is used by JAVA and ANDROID for classes.
Does anyone have an reference material that explains why the standard notation was chosen? One would think it would have been easier to parse a FQDN of the form tld.domain.subdomain.name; but then it may have been easier to discuss appending domains when resolving names.
And as a totally hypothetical exercise, if you had complete control - how would you redesign FQDNs?
