*: Security policies cannot use IP addresses, only hostnames.  (If you use NO_DNS=TRUE, the "hostnames" are actually reformatted IP addresses, and you can match against those.)
 *: You must set NETWORK_INTERFACE to a specific IPv6 address.
 
+Possibly limitations:
+
+*:You must have valid IPv6 (AAAA) DNS and reverse DNS records for the computers.  (NO_DNS=TRUE removes this limitation.)

 {section: Notes}
 
 *: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").
