I suspect the easiest thing to do would be to write some code to query a 
looking glass, perhaps even install your own for this....

but automatically blocking AS's that send some 1434/udp traffic your way
sounds like a really bad idea and would setup an easy way to DoS your
network by "tricking" you into blocking certain AS's.  Why not just block
1434/udp at your ingress points and be happy?
