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 '-'.
+For IPv6 address, it follows same scheme. ':' character in IPv6 address will be changed to '-'. For example, if the IP address is fe80::862b:2bff:fe98:65f2 and DEFAULT_DOMAIN_NAME is nodns.com, the hostname is fe80--862b-2bff-fe98-65f2.nodns.com. (notice that there is one '::' for zero compaction)
 
 When converting NODNS hostname to IP address, we follow those criteria.
