We added preliminary IPv6 support to Condor 7.7.4.  As of 7.7.4, this functionality is experimental and is disabled by default.  You can enable the support if you would like to try it out.
 
+{section: Limitations}
+
+*: Microsoft Windows is not supported
+*: Mixed IPv4/IPv6 pools are not yet supported.
+*: You must use NO_DNS=TRUE, with all of those ramifications.
+*: You must set NETWORK_INTERFACE to a specific IPv6 address.
+
+{section: Notes}
+
+*:In places where Condor is expecting an IP address and a port (e.g. "192.168.0.1:9618"), IPv6 addresses must be wrapped in [square brackets] (e.g. "[fe80::862b:2bff:fe98:65f2]:9618").
