PostgreSQL BIND-9 SDB interface is an enhanced version of the original pgsqldb interface which is included with the BIND-9.1.3. This patch allows you to store all your zone data in a PostgreSQL database rather than in text files. This even makes changes visible immediately without restart/reload of the named server. It also includes PL/SQL functions and triggers to simplify reverse updates.
BGPHist is a tool that receives MP-BGP updates, decodes them, and writes them to a database for logging and monitoring purposes. It supports not only Internet routes, but also IPv4 VPN, IPV6 VPN, and L2VPN. It sounds text output, MySQL databases, and Oracle databases. For the MySQL backend, there is also a simple PHP frontend. It could be used to monitor and log an ISP's customer activity for Internet and VPNs, as a passive BGP looking glass, or as a backend for some external monitoring and accounting system.
