The short answer is no.

To give you an idea of how much debatehas occurred over that 
question, that question was considered inside the IETF (the de facto 
Internet engineering standards body) for over 5 years and there was 
no positive or really definitive outcome.

In 2000 this proposal was submitted 
http://tools.ietf.org/html/draft-senie-inaddr-required-00 and was 
revised over the period of 5 years to be this proposal (within one of 
the official working groups) 
http://tools.ietf.org/html/draft-ietf-dnsop-inaddr-required-07). 
Still, no RFC emerged from all this (meaning it failed to pass all of 
the review cycles).

You may notice the title changed from :

Requiring DNS IN-ADDR Mapping

to

Encouraging the use of DNS IN-ADDR Mapping

and even that wasn't agreed upon.

Ever get the feeling that someday if you google for your own life story,
you'll find that someone has already written it and it's on sale at Amazon?
