        NetworkAddress

NetworkAddress(addr, port=0, family=PR_AF_INET)

:Parameters:
    addr : string or integer
        may be an int or a string.
    port : integer
        port number
    family : integer
        one of:
            - PR_AF_INET
            - PR_AF_INET6

If addr argument is a string it may be either a numeric address or a
DNS host name and is passed to the `AddrInfo` constructor along with
the family parameter. The first address in the `AddrInfo` object is
selected. If you need more fine grained control over which address is
selected from the `AddrInfo` object then invoke `AddrInfo` and select
one of the `NetworkAddress` it provides.

If the addr argument is an integer it may be one of the following constants:

PR_IpAddrNull
    Do not set the IP address, only set the port.
    NetworkAddress(PR_IpAddrNull, 123) is equivalent to NetworkAddress(port=123)

PR_IpAddrAny
    Assign logical PR_INADDR_ANY to IP address. This wildcard value is typically
    used to establish a socket on which to listen for incoming connection requests.

PR_IpAddrLoopback
    Assign logical PR_INADDR_LOOPBACK. A client can use this value to connect to
    itself without knowing the host's network address.
PR_IpAddrV4Mapped
    Use IPv4 mapped address

The optional port argument sets the port number in the NetworkAddress object.
The port number may be modfied later by assigning to the port attribute.

Example::
    
    netaddr = nss.io.NetworkAddress('www.python.org')
    print '%s %s' % (netaddr, netaddr.hostname)
    netaddr = nss.io.NetworkAddress('82.94.237.218')
    print '%s %s' % (netaddr, netaddr.hostname)
    
    Output:
    82.94.237.218:0 www.python.org
    82.94.237.218:0 dinsdale.python.org

**WARNING:** NetworkAddress initialization from a string only works with IPv4
and its use should be considered *deprecated*. Use `AddrInfo` instead.

:Parameters:
    addr : string
        the address string to convert
    family : integer
        one of:
            - PR_AF_INET
            - PR_AF_INET6
            - PR_AF_UNSPEC

Reinitializes the NetworkAddress object given a string.
Identical to constructing nss.io.NetworkAddress() with a
string value (see `NetworkAddress` constructor for documentation).
