BIND resource records allow an explict TTL value that will override the zone file’s TTL for that specific resource record. One use for this is to prevent non-authoritative servers from caching these records, perhaps in prelude to changing a server’s IP address.

To set the TTL for an address record to 1 (the minimum recommended value), use:

chef.tech-recipes.com. 1 IN A 192.168.5.100

Other resource records can have the overriding TTL set in the same manner:

tech-recipes.com. 1 IN MX 10 mx1.tech-recipes.com.
