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.
Asynchronous DNS Resolver for Haskell is a library that provides an asynchronous DNS resolver on top of GNU ADNS. Not all options are supported, but A, MX, and PTR lookups work nicely. There is also support for retrieving generic RR types, CNAMEs, and for NSEC zone walking. The library can be expected to work with fine ADNS 1.4 or later. It might also work with version ADNS 1.3, but that hasn’t been tested.
The LogicBoxes API is a full-control set of programming interfaces that allow you and your resellers to develop your own Website and control panels and integrate them into LogicBoxes OrderBox. Every function of LogicBoxes OrderBox is exposed via the OrderBox API. You can duplicate any or all of the functionality at your end by integrating into the API. The API comes with a specification, client side kits, sample forms, sample code, and complete documentation. Integrating with the API is a breeze. The API is based on SOAP/WSDL. Client side kits are available in PHP, Perl, ASP.NET, and Java. Additionally, since the protocol is standards-based, the API is truly platform independent. Monitoring systems prevent API abuse and any denial of service attacks on the API servers. The API is scalable and secure.
Net::DRI is an object-oriented Perl library with a uniform API to access services from domain name registries/registrars/resellers. With protocols (RRI, RRP, EPP, and XCP), it handles EU, BE, SE, PL, WS, MOBI, AERO, CAT, US, COM, NET, ORG, BIZ, INFO, COOP, LU, AT, FR, NAME, NU, ASIA, TV, CC, AU, UK, NO, DE, CH, LI, HN, SC, VC, AG, BZ, LC, MN, ME, CZ, TRAVEL, PRO, JOBS, BR, PT, SI, IM, IT, CO.CZ, TC, VG, GD, NL, AU, CA, GL, CentralNIC, and CoCCA, all with extensions. It can also perform Whois queries, domain availability checks (DAS), ENUM registrations (IENUM +43) and validations, IRIS DCHK (RFC 3981 and 5144) for .DE, and operations through the APIs of BookMyName, OVH, Gandi, AdamsNames, and OpenSRS. It also includes a shell to leverage all its power without a single line of code. It has a flexible and robust logging framework, and handles internationalization issues, DNSSEC, and IPv6.
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.
