Gerry McLarnon commented on NET-262:
------------------------------------

Hi,

First of all may I apologise if this is not the appropriate route to  
contact you regarding the Apache Commons Net project.

Secondly I'd like to thank you for your work on the Commons Net. It  
has saved me a fair amount of work.

I have one question, is there a version 2.1 available for download as  
mentioned in https://issues.apache.org/jira/browse/NET-305 and other  
places that fix some CIDR notation issues?

I've come across a version created by you ... http://svn.apache.org/viewvc/commons/proper/net/tags/NET_2_1_r924745/src/main/java/org/apache/commons/net/util/SubnetUtils.java?view=markup

Thanks, gerry

> SubnetUtils does not handle /31 and /32 CIDRs well.
> This should be documented and/or fixed.
> 192.168.0.1/32 causes an IllegalArgumentException to be thrown (by the way, that should
show the upper and lower bounds)
> 192.168.0.3/31 gives 
> addressCount=0, 
> low =192.168.0.3 
> high=192.168.0.2
> and 192.168.0.3 is rejected as not in range
