{section: IPv6 support in External Libraries}
 
 {subsection: Unsupported}
-*:srb : they use sockaddr_in and inet_ntoa in many areas. wondering whether Condor uses that exact library.
+*:srb : IPv4 only.
+
+SRB is used by stork, file transfer software. It is developed by the DICE group. (a combination of U of North Carolina at Chapel Hill and UC San Diego) http://www.sdsc.edu/srb/index.php/Main_Page
+
+I guess for now we cannot use SRB on IPv6 port. I hope it won't be any big problem.

 *:gcb : IPv4 only.
