dnsjava is an implementation of the DNS protocol in Java. It supports all of the common record types. dnsjava provides both high and low level access to the resolver. The high level functions perform queries for records of a given name, type, and class, and return an array of records. A cache is used to reduce the number of queries sent. The low level functions allow direct manipulation of dns messages and records, as well as allowing additional resolver properties to be set. A 'dig' clone, dynamic update program, and basic server are also included. Extensions to the DNS protocol are supported as well (DNSSEC, TSIG, EDNS0).
Domain Technologie Control (DTC) is a Web-based control panel for hosting that can delegate the task of creating subdomains, email, and FTP accounts to users for the domain names they own. It has support for many programs, including bind 8 and 9, MySQL, Apache, PHP 4, qmail, Postfix, Courier, Dovecot, ProFTPD, Webalizer, and mod-log-sql. It can also generate backup scripts, calculation scripts, and config files using a single system UID/GID, and monitor all traffic accounting per user and per service. It is fully skinnable and translated into several languages.
PHPresolver is a DNS resolver library written in pure PHP. It may help you code email address validity verification under the Win32/BeOS port of PHP because the current version has no support for DNS-related functions such as getmxrr() or checkdnsrr(). In addition, the library partially supports IPv6 address resolution.
GNU Libidn is an implementation of the Stringprep, Punycode, and IDNA specifications defined by the IETF Internationalized Domain Names (IDN) working group. It is used to prepare internationalized strings (such as domain name labels, usernames, and passwords) in order to increase the likelihood that string input and string comparison work in ways that make sense for typical users throughout the world. The library contains a generic Stringprep implementation that does Unicode 3.2 NFKC normalization, mapping and prohibition of characters, and bidirectional character handling. Profiles for iSCSI, Kerberos 5, Nameprep, SASL, and XMPP are included. Punycode and ASCII Compatible Encoding (ACE) via IDNA are supported.
PHP Net_IDNA is a class to convert between the Punycode and Unicode formats. Punycode is a standard described in RFC 3492 and part of IDNA (Internationalizing Domain Names in Applications [RFC3490]) . This class allows PHP scripts to convert these domain names without having one of the PHP extensions installed. It supports both IDNA 2003 and IDNA 2008.
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.
Avahi is a framework for Multicast DNS Service Discovery (mDNS/DNS-SD a.k.a. Zeroconf) on Linux. It allows programs to publish and discover services running on a local network with no specific configuration. For example, you can plug into a network and instantly find printers to print to, files to look at, and people to talk to.
WAWAS is a full PHP application server. The main server core listens to any IP/port and passes data to any mounted protocol on the listener. Implemented protocols are HTTP1.1/1.0, Comet, Telnet, DNS, mail, and FTP. Each protocol runs modules that build response data based on the requests. Memory object persistence allows data and caches to be shared across protocols or time. All configuration uses XML. It can be launched as a daemon, with or without forked workers, and is nearly as fast as Apache in preliminary tests.
