The hath package

[ Tags: agpl, program, utils ] [ Propose Tags ]

Hath is a Haskell program for working with network blocks in CIDR notation. When dealing with blocks of network addresses, there are a few things that one usually wants to do with them:

Hath has several modes to perform these functions:

Regexed
This computes a (Perl-compatible) regular expression matching the input CIDR blocks. It's the default mode of operation.
Reduced
This combines small blocks into larger ones where possible, and eliminates redundant blocks. The output should be equivalent to the input, though.
Duped
Shows only the blocks that would be removed by reduce; that is, it shows the ones that would get combined into larger blocks or are simply redundant.
Diffed
Shows what would change if you used reduce. Uses diff-like notation.
Listed
List the IP addresses contained within the given CIDRs.
Reversed
Perform reverse DNS (PTR) lookups on the IP addresses contained within the given CIDRs.

Examples:

Combine two /24s into a /23:

$ hath reduced <<< "10.0.0.0/24 10.0.1.0/24"
10.0.0.0/23

Create a perl-compatible regex to be fed to grep:

$ grep -P `hath regexed -i cidrs.txt` mail.log

List the addresses in 192.168.0.240/29:

$ hath listed <<< "192.168.0.240/29"
192.168.0.240
192.168.0.241
192.168.0.242
192.168.0.243
192.168.0.244
192.168.0.245
192.168.0.246
192.168.0.247

Perform PTR lookups on all of 198.41.0.4/30:

hath reversed <<< "198.41.0.4/30"
198.41.0.4: a.root-servers.net.
198.41.0.5:
198.41.0.6: rs.internic.net.
198.41.0.7:
