Hello everyone,
I am somehow a newbie with DNS BIND. A system I am trying to ponder on
requires a functionality that somehow fits the RES_BLAST option in

However, as I tried to study parts of the BIND9 code, I find that there
seems to be no implementation. I think this is also mentioned in some dns
tutorial sites on the net.

I do not fully understand the pros and cons of RES_BLAST, but I would like
to know theoretically, why BIND9 has not implemented it yet. I mean if there
is a fatal or severe consequence, when our lookup algorithm is to query all
name servers simultaneously.

Thank you,
