DomainCheck - DCHK
News
 Quellcode Umgezogen
Sämtlicher Quellcode meiner OpenSource-Software ist nun auf GitHub zu finden:

https://github.com/pfedick

Zuvor hatte ich meine Projekte zum Teil in Subversion-Repositories bei Sourceforge und Google-Code. Google hat seinen Dienst jedoch in diesem Jahr eingestellt und von Sourceforge möchte ich aus verschiedenen Gründen schon länger weg. Das Zupflastern mit Werbung (man kann ja kaum noch zwischen Werbung und Download-Button unterscheiden) und das Kapern bekannter Projekte, die Sourceforge verlassen haben, um darüber Malware zu vertreiben, möchte ich nicht länger tolerieren (Quelle: https://en.wikipedia.org/wiki/SourceForge). Der beinahe zweiwöchige Totalausfall im Juli diesen Jahres hat mich dazu gebracht meinen Quellcode zunächst temporär auf einem eigenen Server zu hosten, und jetzt auf GitHub. Die Release-Binaries befinden sich derzeit noch bei Sourceforge, bis ich dafür eine bessere Lösung gefunden habe.
 DENIC to discontinue DCHK service as of 3rd December 2013
Effective 3rd December 2013, DENIC will shut down their Domain Check (DCHK) lookup service which was in place so far to check out the mere registration status of a .DE domain, thus if such domain was registered or not, at the respective time of query.

Given that the protocol underlying DCHK, i.e. the Internet Registry Information Service (IRIS) standard, has never gained a relevant foothold in the market, and therefore DCHK kept being employed by a small number of users only, continuing the service is no longer justifiable, from a cost-benefit point of view.

In the future, all status information concerning .DE domains may further be comfortably accessed via the Domain Query web interface, or the command-line based public-whois service.

DENIC asks for the kind understanding of all users being affected by the DCHK shutdown.
 
About
 What is DCHK?
DCHK is the abbreviation of DomainavailabilityCHecK, and is an IRIS based protocol to query domain status. It is meant as a more formal replacement of the whois protocol.

On this webpage, you can find two things:

1. A DCHK client
The client contains an implementation of the IrisLWZ- and DCHK-protocol, written in C and C++. It is divided in three parts:
  1. a library, which you can use in your own programs
  2. a command line client
  3. a graphical user interface (GUI)

2. A DCHK server
The server is a library written in C++, which you can use as a basis for you own DCHK server. It also contains an example implementation, using a MySQL database as backend.
