6.1.2.1 Resource Records with Zero TTL: RFC-1035 Section 3.2.1
All DNS name servers and resolvers MUST properly handle RRs
with a zero TTL: return the RR to the client but do not
cache it.
- DISCUSSION:
Zero TTL values are interpreted to mean that the RR can
only be used for the transaction in progress, and
should not be cached; they are useful for extremely
volatile data.
