Trailing dot is where the 14 DNS Root Servers are. Each dot before that trailing dot is also an authoritative name server(s).

- fanf2 3y agoNo, dots do not necessarily correspond to zone cuts. The most common counterexample is the IPv6 reverse DNS, but you can also see it in (eg) www.dns.cam.ac.uk which has only three zone cuts.
- egberts1 3y agoI would like to think that Zone cut is vastly different subset of authoritative nameserver. Go down to "DNS Zone Cut" section: https://egbert.net/blog/articles/dns-dnssec-private.html https://egbert.net/blog/articles/dns-dnssec-private.html
- dc396 3y agoWrong on both. There are 13 root servers (operated by 12 different organizations). You don't have to have zone cuts at each dot.
- egberts1 3y agoOops, my bad. Must have counted the shadowy shadowed shadow root servers (ya know, some big enterprise like a backup)
