intelligent NAMED

[besnard michel]

hi,
i'm looking for special features aka intelligent DNS servers ... may be not
included in BIND

i need different DNS responses when différents DNS clients ask the same
request

example :

some DNS clients request for www.test.com
if the source IP of the DNS client is in the
- IP_POOL_1 then my DNS server will response IP_ADDRESS_1
- IP_POOL_2 then my DNS server will response IP_ADDRESS_2
- or by default my DNS server will response IP_ADDRESS_3

i don't want to do load balancing but "geographical" or "zone" load
balancing

regards,
Michel
