Manageable daily work-list.
+1:currently, i have no idea how to divide source codes into chunks. so, rather start with condor_util_lib, which deals heavily with IPv4 address.
+1::take a look at unit test
+1::convert is_ipaddr function
+1::convert convert_ip_to_hostname function
1:discuss with staffs about new sinful string format. <1.2.3.4:80> will not work! encapsulate ipv6 address by [] ? like <[1234:abcd:1234::5678]:5000> ??
1:remove every obsolete interface.
1:change every incidents where use sockaddr,sockaddr_in, and int.
