HTCondorWiki: Ipv Six Work Note Two

 
 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.
+If the config allows to use any network interface, it uses the interface with IPv4 address to connect IPv4 host. It uses the interface with IPv6 address to connect IPv6 host, too!
+
+If the config requires to use IPv4 address, it will bind to the IPv4 socket using IPv6 socket. (IPv4 address should be converted to IPv4-mapped IPv6 address, though) In this case, no IPv6 connection is allowed.
+
+Thus, IPv6 mode is harmless in any case. (in theory)
