[atlas] Wrong IP prefix values accepted?

I've just gone over your cases here and wanted to let you know that at
least one of these was the unfortunate result of a typo on my part :-( 
I've since fixed it, and that fix will go out tomorrow as it's coming up
on 1900h here in Amsterdam.

Unfortunately, the issue of rejecting should-be-valid prefixes was not
as simple a problem and that's going to take a little longer to fix.  We
have a few people tasked now with fixing this.  It's a known problem
with how we handle comparing IPs to prefixes in our database and we hope
to have that working in production tomorrow as well -- though it may
take a smidge longer than that.

Thanks for finding these, and for reporting it.  Though next time,
please report bugs to atlas-bugs at ripe.net :-)
