Classless IP addresses
Download as PDFThe method of allocating address space according to need is known as CIDR. Further information about this strategy may be found in RFC 1519, Classless Inter-Domain Routing (CIDR): an Address Assignment and Aggregation Strategy.
All information sent across the Internet is encapsulated into IP datagrams. At present IPv4 is used: see RIPE-405, the RIPE document for IPv4 Address Allocation and Assignment Policies.
