jresolver is a lightweight domain name resolver library written in pure Java. It is what RFC1034 describes as a stub resolver, i.e. it uses a single nameserver to do the hard work of resolving its queries. It operates using UDP as a transport, and has support for multithreaded querying and a robust resend and timeout mechanism.
OpenVISP Admin is a fork of Postfix Admin. Its aim is to provide a unique ISP tool as a Web panel for end users, postmasters, and site administrator to manage their data. It allows site administrators to update amavisd-new values, spam-assassin values, greylisting, domains checks, and sender verification. It can also provide datacenter admins with a central point of access, by having APC Masterswitch configuration and access, hosting access requests, and PPTP access and statistics views.
nss-mdns is a plugin for the GNU Name Service Switch (NSS) functionality of the GNU C Library (glibc) which provides host name resolution via Multicast DNS (a.k.a. Zeroconf, a.k.a. Apple Rendezvous, a.k.a Apple Bonjour). This effectively allows name resolution by common Unix/Linux programs in the ad-hoc mDNS domain .local.
Zoned manages BerkeleyDB zone databases using the BDB Replication Base API. It manages all node communication and eases the difficulties that BerkeleyDB replication imposes (such as making sure that all zone changes go straight to the master node for transaction processing). It requires the BIND9 DLZ BDBHPT driver.
RIR to DNS converter is a tool to convert Regional Internet Registry data to a DNS country lookup zone. You can use it to build your own DNS zone for looking up country codes from IP addresses. It uses data directly from RIPE, ARIN, APNIC, LACNIC, and AFRINIC. The data can be updated on a schedule of your choosing.
