Why not declare wildcards records at DNS to solve randomness and doing a 
single DNS query ?

Instead of declaring

spammer.com   A  127.0.0.1

you could declare :

spammer.com      A   127.0.0.2
*.spammer.com    A   127.0.0.2

Does this work ?

I run a home rbl and I do this to block an entire IP class.
