 Hmm... formatting helps.  Running everything together makes it hard to read.

  That's good.

> I'm trying to use the client library to talk over IPv6.  First, I am using one of the included applications such as radiusclient or radlogin to establish a baseline to work with.  When I try to send a radius request with one of these applications, I see in my system's log:rc_get_ipaddr: couldn't resolve hostname: feedThis would be for an address such as "feed:beef::17:18:20:10".  Looking into the code, it appears that it is expecting IP:Port:Secret and it is parsing the first part of the IPv6 address as the whole address.  Looking into the code on github, I see that there is a block in the source intended to deal with [IPv6]:Port:Secret form.  I do not see this code in the 1.1.7 tarsal.

  We should release a new version soon.

  It's a problem with 1.1.7.  Use the version from github.

>  I see in the release notes: "Added support for IPv6. Patch from Nikos Mavrogiannopoulos."  Browsing in the github repo, I see the commits from Nikos that add support for IPv6 along with the comment "Added support for connecting and listening to IPv6 addresses."  This commit is from March and I can not find the associated code from the commit in the 1.1.7 tar ball I downloaded.  Am I misunderstanding the release note or is IPv6 support I'm looking for actually not in the 1.1.7 release?

  The framework for IPv6 is there.  Some bits are missing.
