Actually the root is a null (empty) label rather than "."; dots are delimiters of labels, there is an empty label after "." in FQDNs. See RFC 1034 Section 3.1.

- c0pium 3y agoHaving all addresses be rooted in an untypeable null isn’t much better.
- jesprenj 3y agoIt is not null, it's an empty string.
- c0pium 3y agoYou should read the referenced RFC, it’s right there. “””Because all domain names end at the root, which has a null string for a label…”””
- paulddraper 3y ago"null string" or "nil string" or "empty string" are all the same thing. IDK why we're even talking about this though.
