IP address is no longer fixed 4 bytes nor fixed 16 bytes. It can be both of them. So, every storage class should be changed. For some of source codes that use 'int' as storage for IP address, this is most troublesome because it could be hidden to simple text search.
+Reading and parsing IP address from config file should be changed as well.
+
+IPv6 address string is far longer than IPv4 address. IPv6 address [0001:0002:0003:0004:0005:0006:0007:0008], length is 41. IPv4 address 101.202.103.203, length is 15. About 3 times longer.
+
+Printing IP address to log file should be considered since existing layout may not work well.

{section: Current Condor Code Base}
sockaddr_in is used in many areas and also unsigned long is used to hold IP address.
-{linebreak}
-{linebreak}

There are many places to change. For example, in sock.h,{linebreak}
{code}
unsigned int Sock::get_ip_int()
