Out of curiosity, how are you blacklisting outside of SIMS?
I run a local DNSBL.
As I understand it, I can define DNS records of the form [EMAIL PROTECTED] --> 127.0.0.2 to define 24.4.2.1 as a bad address.
Not quite. Try a . instead of the @
Is there some similar syntax for blocking a CIDR address range?
That depends on the DNS server. For BIND, there is no generalized CIDR wildcarding but there is domain wildcarding so you can do things like this:
$ORIGIN 24.blackholes.my.domain * IN A 127.0.0.2
BIND also has a $GENERATE directive for DNS records to do range-based wildcards.
Other name servers can do other things.
