Constructor Detail

NetAddr

public NetAddr(String optAddr)
        throws UnknownHostException

Enabled: Construct a NetAddr from a string in the form: hostname:portnumber or hostname. If the :portnumber is omitted, port number 0 will be assumed. The hostname may be either a DNS name or an IP number in dotted decimal format. It may be both of these separated by a slash, in which case only the part after the slash is significant. If the significant part of the hostname is absent, then the port is associated with all local IP addresses.

Examples:

   "the-earth.communities.com/205.162.51.187:4568"
   "the-earth.communities.com:4568"
   "205.162.51.187:4568"
   "the-earth.communities.com"
   ":4568"
   ""
   null
 

Parameters:

optAddr - is the network address.

Throws:

UnknownHostException - is thrown if the host name can not be resolved.

public NetAddr(InetAddress optIP,
               int portNumber)
