Do you mean a CIDR calculator?
If so, I put a rudimentary implementation into [net] 2.0 last year.
See the implementation here:
http://svn.apache.org/viewvc/commons/proper/net/branches/NET_2_0/src/main/java/org/apache/commons/net/util/SubnetUtils.java?revision=740965&view=markup
And example usage:
http://svn.apache.org/viewvc/commons/proper/net/branches/NET_2_0/src/main/java/examples/SubnetUtilsExample.java?revision=658518&view=markup
Is that what you mean?

Hi Robert
Sounds great .... a DNS client was one area I felt could be added to
[net] for a while now (the other being ssh/scp support).
Can you point me to the existing client code in james?
If I remember correctly the code Robert is talking about is not a DNS
client but a Network Matching utility (e.g: is 127.5.2.6 part of
127.0.0.0/8 network ?).
It uses some java.net.InetAddress function, but does not act as a
DNSclient.
About DNS clients, if you need a dns client that uses correct caching
(java itself have plenty of issues with DNS caches) dnsjava is already
around and very solid.

over in james, we have some useful DNS client code. sufficiently useful
for the qpid to enquire about the possibility of sharing it:
http://markmail.org/thread/u4n4q5f2q7wyq2vf. i think it should probably
be in scope for commons-net, though DNS is not (at the moment) a
supported protocol.
there are some wrinkles (aren't there always?) in that the code in
question has been rewritten for 3.x to use a separate DNS service to
avoid know limitations of the java DNS client implementation. it uses
http://sourceforge.net/projects/dnsjava/ (unfortunately this isn't very
actively maintained).
but the 2.x version is solid enough and is very suitable for a
microlibrary
i'd be willing to help out (if that'd be helpful) and possible a few
other committers from james and qpid may be willing to help maintain
this code as well.
opinions?
