Each link-local address (which can be identifiable by looking at the address) will be bound to pre-configured NETWORK INTERFACE.
+{section: NODNS and IPv6}
+
+In NODNS mode, hostname is set by machine's IP address and DEFAULT_DOMAIN_NAME from condor_config. For example, if the IP address of the machine is 127.0.0.1 and DEFAULT_DOMAIN_NAME is nodns.com, the hostname is 127-0-0-1.nodns.com
+
+For IPv6 address, it follows same scheme. ':' character in IPv6 address will be changed to '-'.
+
+When converting NODNS hostname to IP address, we follow those criteria.
+
+1) if there are 7 dashes in the hostname, it is IPv6 address
+2) if there is '--' in the hostname, it is IPv6 address.
+
+Valid IPv6 address will always contain 7 colons or one '::' (which compacts multiple zeroes). Thus, we can determine the type of address without confusion.

{section: network_adapter.* and IPv6}
Current method of getting network adapter is totally incompatible with IPv6 address. Current Condor uses ioctl() with SIOCGIFCONF that only returns IPv4 addresses.
