What dictates how long another name server caches the authoritative name
server for a domain? I was under the impression it was the default
time-to-live, but I have a situation where an authoritative name server
was removed from service several days ago, yet queries to it continue. Dig
is correctly reporting the new authoritative name servers for the domain
in question. How common is it for DNS servers to ignore the ttl?
