HTCondorWiki: How To Enable Ipv Six

 *: Microsoft Windows is not supported.
 *: Mixed IPv4/IPv6 pools are not supported.
 *: Security policies cannot use IP addresses, only hostnames.  (If you use NO_DNS=TRUE, the "hostnames" are reformatted IP addresses, and you can match against those.)
-*: You must set NETWORK_INTERFACE to a specific IPv6 address.
+*: You must set NETWORK_INTERFACE to a specific IPv6 address.  It is not possible to use multiple IPv6 interfaces on a single computer.
 
 Possibly limitations:
 
 *:You must have valid IPv6 (AAAA) DNS and reverse DNS records for the computers.  (NO_DNS=TRUE removes this limitation.)

-*:Unless otherwise specified, when Condor is expecting an IP address (e.g. "192.168.0.1", you must put IPv6 addresses in [square brackets] (e.g. "[fe80::862b:2bff:fe98:65f2]").  If there is a port, it is placed outside of the brackets (e.g. "[fe80::862b:2bff:fe98:65f2]:9618").
-*:When using NO_DNS, IPv6 addresses are turned into hostnames by taking the IPv6 address, changing colons to dashes, and appending DEFAULT_DOMAIN_NAME.  So 2607:f388:1086:0:21b:24ff:fedf:b520 becomes 2607-f388-1086-0-21b-24ff-fedf-b520.example.com (assuming DEFAULT_DOMAIN_NAME=example.com)

 ENABLE_IPV6 = TRUE

-# This should be the IPv6 interface for this computer.
-# Do not put [square brackets] around this address.
+2: Specify the IPv6 interface to use.  Note, do _not_ put [square brackets] around this address.
+{code}
 NETWORK_INTERFACE = 2607:f388:1086:0:21b:24ff:fedf:b520

-# This is the NO_DNS style name for the central manager
-CONDOR_HOST = cm.example.com
-# Also acceptable would be the collectors IPv6 address, like the following.
-# However, by using the IP address, you can no longer specify your
-# security policy in terms of $(CONDOR_HOST)
-#CONDOR_HOST =[2607:f388:1086:0:21e:68ff:fe0f:6462]
+{section: Additional Notes}
+
+If you specify =CONDOR_HOST= or =COLLECTOR_HOST= as an IP address, you must put the address, but not the port, in square brackets.  You can continue to specify hostnames.  For example:
+{code}
+CONDOR_HOST =[2607:f388:1086:0:21e:68ff:fe0f:6462]
+# This configures the collector to listen on the non-standard port 5332.
+COLLECTOR_HOST =[2607:f388:1086:0:21e:68ff:fe0f:6462]:5332
 {endcode}
+Because IPv6 addresses are not supported in the security settings, you will be unable to use =$(CONDOR_HOST)= or =$(COLLECTOR_HOST)= in your security configuration if you specify an IP address.
+
+When using NO_DNS, IPv6 addresses are turned into hostnames by taking the IPv6 address, changing colons to dashes, and appending DEFAULT_DOMAIN_NAME.  So 2607:f388:1086:0:21b:24ff:fedf:b520 becomes 2607-f388-1086-0-21b-24ff-fedf-b520.example.com (assuming DEFAULT_DOMAIN_NAME=example.com)
