GW-ETH-02A
IQRF DNS
IQRF DNS server is provided by the MICRORISC s.r.o. and is intended as a replacement of the the Dynamic DNS
server. It allows users a remote connection to an eqiupment (within Internet) without knowing current public IP
address of the equipment. If the equipment is configured and local redirection is set properly, it is possible to use the
IQRF DNS names instead of IP addesses of the equipment in web browsers - see the example below. The only thing
what the user should know, is the MAC address of the equipment. In following explanation the MAC address
001FD5010203 and IP address 10.100.20.200 are used.
Registering the equipment in the IQRF DNS server database
http://www.iqrfdns.org/?IDIP=001FD5010203
The GW-ETH-02A client sends this command automatically and regularly (if this is activated in the GW setup) which
keeps a record of MAC address of the equipment and corresponding IP address (for remote GW connecting) in the
server database. The server responds with public IP address which the command was sent from. Thus, the
equipment finds out its public IP address in the format:
Current IP Address: 10.100.20.200
Request for IP address
http://www.iqrfdns.org/?IP=001FD5010203
The http client of the GW-ETH Tool program sends this command to find out the IP address assigned to given MAC
address in the server database. The server returns the result in the format:
Requested IP Address: 10.100.20.200
If the MAC address is not found in the database the server returns:
IQRFDNS Message: Reguested device is not registered.
Connection to the equipment - redirection
http://www.iqrfdns.org/?ID=001FD5010203
The command is intended to be entered to the www browser for connection to www interface of the GW-ETH-02A.
The server finds requested ID (MAC address) in the database and redirects it to assigned IP address. The GW must
have set and activated the IQRF DNS server as the DDNS.
If requested ID is not found the server returns:
IQRFDNS Message: Reguested device is not registered.
If there is no answer from the GW after redirection the server returns:
IQRFDNS Message: Device is not responding. It is either offline or its IP address has changed. Try it again after
xx:xx min.
