Remarks
This class represents an Internet Protocol version 4 (IPv4) address. Defined by RFC 790: Assigned Numbershttp://www.ietf.org/rfc/rfc790.txt, RFC 1918: Address Allocation for Private Internetshttp://www.ietf.org/rfc/rfc1918.txt, and RFC 2365: Administratively Scoped IP Multicasthttp://www.ietf.org/rfc/rfc2365.txt<h3> "format">Textual representation of IP addresses</h3>
Textual representation of IPv4 address used as input to methods takes one of the following forms:
<blockquote><ul style="list-style-type:none"> <li>d.d.d.d</li> <li>d.d.d</li> <li>d.d</li> <li>d</li> </ul></blockquote>
When four parts are specified, each is interpreted as a byte of data and assigned, from left to right, to the four bytes of an IPv4 address.
When a three part address is specified, the last part is interpreted as a 16-bit quantity and placed in the right most two bytes of the network address. This makes the three part address format convenient for specifying Class B net- work addresses as 128.net.host.
When a two part address is supplied, the last part is interpreted as a 24-bit quantity and placed in the right most three bytes of the network address. This makes the two part address format convenient for specifying Class A network addresses as net.host.
When only one part is given, the value is stored directly in the network address without any byte rearrangement.
For methods that return a textual representation as output value, the first form, i.e. a dotted-quad string, is used.
<h4> The Scope of a Multicast Address </h4>
Historically the IPv4 TTL field in the IP header has doubled as a multicast scope field: a TTL of 0 means node-local, 1 means link-local, up through 32 means site-local, up through 64 means region-local, up through 128 means continent-local, and up through 255 are global. However, the administrative scoping is preferred. Please refer to RFC 2365: Administratively Scoped IP Multicasthttp://www.ietf.org/rfc/rfc2365.txt
