PeeringDB is a freely available, user-maintained, database of networks, and the go-to location for interconnection data. [2] The database facilitates the global interconnection of networks at Internet Exchange Points ( IXPs ), data centers, and other interconnection facilities, and is the first stop in making interconnection decisions.

The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
One simple approach is the Electronic Number Mapping System (ENUM), developed by the IETF, using existing E.164 telephone numbers, protocols and infrastructure to indirectly access different services available under a single personal identifier. ENUM also permits connecting the IP world to the telephone system in a seamless manner.
A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [2] (routable only within the scope of private networks, but not the global IPv6 Internet). Because they are not globally reachable, ULAs are somewhat analogous to IPv4 private network ...
In a relational database management system this could be through a stored procedure. Precondition: max_lo must be set to a value greater than zero. algorithm generate_key is output: key as a positive integer if current_lo ≥ max_lo then current_hi := get_next_hi() current_lo := 0 key := current_hi × max_lo + current_lo current_lo := current ...
Additionally, the U.S. Federal Communications Commission (FCC) has proposed that geolocation software might be leveraged to support 9-1-1 location determination. [8] An IP address or the related unique URL may also be investigated with basic functions, typing from the keyboard two instructions: ping and traceroute. [9]
Since the pool of available public IPv4 addresses is depleted, it is no longer possible for most ISPs to assign unique IPv4 addresses to CPEs, because there are none left to them to acquire. Instead, an address in the 100.64.0.0 / 10 range is assigned on the CPE's Internet-facing interface, and this address is translated again to one of the ...
