* These coded instructions, statements, and computer programs are the
* httpAddrLocalhost() - Check for the local loopback address.
* httpAddrLookup() - Lookup the hostname associated with the address.
* _httpAddrPort() - Get the port number associated with an address.
+ * _httpAddrSetPort() - Set the port number associated with an address.
* httpAddrString() - Convert an IP address to a dotted string.
* httpGetHostByName() - Lookup a hostname or IP address, and return
* address records for the specified name.
