Addressing & Routing
Allows continued expansion of the Internet
- Expanding IP addresses to 16 bytes insures that the Internet will not run out of addresses in the foreseeable future
Improves routing efficiency
- Longer IP addresses allow for aggregating addresses by hierarchies of network, access provider, geography, corporation, and other groupings
- Such aggregation should increase router look-up speed and reduce router memory requirements, making routing more efficient
Accommodates non-IP addressing formats
- The long address space provides adequate room for translations of IPX, NSAP, Ethernet and other non-IP addresses into IPv6 addresses
- This allows existing networks to connect to the Internet with a minimum of address reconfiguration and reduces set-up, debugging, and maintenance loads on network managers
