This module is subject to page protection.It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.
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.
These databases typically contain IP address data, which may be used in firewalls, ad servers, routing, mail systems, websites, and other automated systems where a geolocation may be useful. An alternative to hosting and querying a database is to obtain the country code for a given IP address through a DNSBL-style lookup from a remote server.
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).

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 ...
DBD (DataBase Driver) modules serve as plug-ins to DBI, allowing programmers to use near-database-independent SQL code in their applications. Programmers can also use the DBI and DBD modules indirectly using one of the object-relational mappers available for Perl, such as DBIx::Class, for more database-independent code with no need to write SQL.
