DNS request for RR “ANY”

0

I've seen a trace where the DNS resolver asks for "ANY" information from the name server. Any idea about the practical case for such request ? In which context does this happen ?

It happens when someone wants to ask a DNS server for all available information to a domain in a single request. Most programs don't use it, but manual queries often do, because it gets results faster than querying each single type (A, AAAA, NS, MX,...) sequentially.
