One interesting piece not mentioned is how updating the name servers at your registrar is communicated to the top-level domain (TLD) registry operator's name servers (ex: Verisign's for .com). The answer, for .(com|net|org) at least, appears to be that the registrar makes an [EPP][^1] request on your behalf. The protocol is documented in IETF std69 -- specifically [RFC5731][^2]. What I'm not clear on is whether other methods are still in common use. I'm also curious what the process looked like before EPP. If someone else here knows, I'd be interested in learning.

EPP is still very much in use as ICANN requires it for gTLDs[0] (2012 round), sTLDs[1] (2000 & 2003 rounds). And most uTLDs[2] (non ccTLDs before 2000, e.g. .com) have moved over due to consolidation / negotiation / cajoling by ICANN. ccTLDs[3] are free to chose their own provisioning process / protocols; some use EPP, some don't.
