I don't think any name server uses some kind of SQL for DNS lookups
because accessing a database on disk is usually too slow. [A busy name
server gets over 100 queries/second and if a database lookup can be
done in a single disk I/O which takes 10ms....] Having said that,
using a database could be useful for huge zones - like .com - that
have large numbers of names that are rarely looked up. The commonly
used ones could be held in memory after getting fetched from disk.
BIND9 - currently in beta test - has hooks to allow zone data to be
retrieved from a database with and access method such as SQL. However
I'm not aware of any implementation which exploits these hooks.
