parse

Creates a new SocketConnectable for connecting to the given hostname and port.

May fail and return null in case parsing host_and_port fails.

host_and_port may be in any of a number of recognised formats; an IPv6 address, an IPv4 address, or a domain name (in which case a DNS lookup is performed). Quoting with [] is supported for all address types. A port override may be specified in the usual way with a colon.

If no port is specified in host_and_port then default_port will be used as the port number to connect to.

In general, host_and_port is expected to be provided by the user (allowing them to give the hostname, and a port override if necessary) and default_port is expected to be provided by the application.

(The port component of host_and_port can also be specified as a service name rather than as a numeric port, but this functionality is deprecated, because it depends on the contents of /etc/services, which is generally quite sparse on platforms other than Linux.)

Parameters:

host_and_port	the hostname and optionally a port
default_port	the default port if not in host_and_port

Returns:

the new NetworkAddress, or null on error
