DomainCheck - DCHK DomainCheck


 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.
