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:
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.
Please Note: The Windows version will need Windows XP or above. It does not run on Windows 2000. See FAQ for more information.
