That's right.
Basically:
Let a, b, c, d be 0, ..., 255.
1. If *.a.rbl.maps.vix.com (without globbing the *) has answers,
this means that $a.x.y.z is listed, for all values of x, y, z.
Print positive response, increment a, go to step 1.
2. If *.a.rbl.maps.vix.com (again without globbing) has errors,
this means that $a.x.y.z is not listed, for all x, y, z.
Increment a, go to step 1.
3. If *.b.a.rbl.maps.vix.com has answers, print positive response,
increment b, go to step 3.
4. If *.b.a.rbl.maps.vix.com has errors, increment b, go to step 3.
5. If *.c.b.a.rbl.maps.vix.com has answers, print positive response,
increment c, go to step 5.
6. If *.c.b.a.rbl.maps.vix.com has errors, increment c, go to step 5.
7. If d.c.b.a.rbl.maps.vix.com has answers, print positive response.
8. Increment d, go to step 7.
Items 1 and 2 are the real speedups, especially 2.
! In other words, did anyone actually try?
Not yet. I may get around to it though.
