Domaincheck: DENIC makes available new information service for querying domains
2008-09-19
Domaincheck shall replace whois information service ? New standard was
developed in close collaboration with DENIC
19.09.2008 - Starting 23 September 2008, DENIC will place at disposal an
implementation of the so-called "Domaincheck" service. So DENIC will be the
first domain registry to break new ground in this field: It plans to substitute
the high-performance Domaincheck (DCHK) for the known information service whois
in the medium term. The DCHK specification, published at the start of 2008, is
based on the IRIS standard (Internet Registry Information Service), which needed
several years of intensive work to be established. As a member of the IETF
Working Group CRISP (Cross Registry Information Service Protocol), DENIC's
employee Marcus Sanz took a leading role in formulating IRIS.
The Domaincheck offers the Internet user numerous advantages. One fundamental
benefit is the fact that it uses XML (Extensible Markup Language) for the
standardized and structured query of a domain's availability. At present, the
whois servers of the various registries respond to queries in different ways.
This is due in particular to the lack of a standardized format of the queries
and responses and to the fact that the stored information is output in an
unstructured way. So access software has to be able to process all those
response types. With the standardized request and response schemes of IRIS it
will become much easier to develop new applications, which can also be used more
universally. Querying domain data-bases of various Top Level Domains will also
be greatly facilitated, since the clients will be able to identify the correct
server automatically on the basis of the information provided by the Domain Name
System (DNS).
The Domaincheck also offers economic benefits to the registries. Using the IRIS-LWZ
protocol, which does not only provide the User Datagram Protocol (UDP) for a
speedy exchange of data but also a special compression algorithm, leads to a
reduction in server data traffic, in particular in case of large query volumes,
as they are common in nearly all registries today. This increases the
availability of the service, which in turn is beneficial to the Internet user.
The pilot implementation of DENIC currently is the only one that makes the
Domaincheck function avail-able. To enable the user to query the server, DENIC
places at disposal a client with user manual for downloading under
http://domaincheck.denic.de. The
servers as well as the access program will be gradually developed into a fully
efficient IRIS service.
