yes, I'm working on it.
+{section: IPv6 Mode}
+
+Phase 3 is gonna have IPv6 mode. IPv6 mode basically makes Condor to prefer IPv6 address.
+
+With IPv6 mode turned on, Condor will create every socket as IPv6. (AF_INET6)
+
+However, it is still possible to interact with IPv4 Condor and also is possible to bind to IPv4 address!
+
+With IPv4 address and IPv6 mode, Condor will use IPv4-mapped IPv6 addresses.
