Verifying DNS-server (nslookup)

nslookup ( Server name lookup search on the name server) :- A utility that provides a user command line interface to access the DNS system. Allows you to specify different types of queries and query tells the server randomly. Its counterpart is the utility host and dig. Developed as part of a package BIND (for UNIX-based systems) and ported to Microsoft for Windows-based systems, installed with the operating system.

To test the DNS-server (notably, this applies to your ISP), type the following command:

C: \> nslookup – replace with your domain name.

The results of the command should be something like this:

Server: ns1.hhhhhhhhhh.hhh Address: hh.hh.hh.hh Non-authoritative answer: Name: Address: 115.XXX.XXX.10

Such a response indicates normal functioning of the dedicated hosting server DNS, that is, name resolution is passed correctly and the DNS-server of your provider correctly defined IP-address of the server of our hosting (example: 115.XXX.XXX.10), which is the site (at this writing, the addresses are different for different servers).

If the IP-address is incorrect or if you received an answer form:

Server: ns1.hhhhhhhhhh.hhh Address: hh.hh.hh.hh *** ns1.hhhhhhhhhh.hhh can’t find : Non-existent domain

This suggests that there are problems in the process of domain name or DNS-server of your provider that has not yet updated their records (usually takes no more than two days). If this situation persists for longer, we recommend you to contact your provider and report a problem with the DNS-servers and be sure to notify the Technical Support of service provider.

If you or a domain administrator, self-performed actions on the registration of a domain name – check DNS settings .

If any of you do not understand, check with system administrator on duty round the clock for technical support services.
