    So when you enter a domain name, for instance, , it’s respective IP address is mapped with the help of DNS and the webpage is loaded accordingly. Some command options require a DNS zone transfer, which often is not allowed by the DNS server. Be aware of this, particularly for external name resolution servers or other DNS servers you don’t manage. What might make you suspect a name resolution problem? Perhaps a user comments that they can no longer reach a resource such as a file server or printer, or an email server seems unavailable. Users may experience intermittent difficulty accessing an internal web server or related service. Perhaps users can connect to a server, but it isn’t the correct server, so an unexpected web page is displayed. Consul versions 1.5.2+ can be configured to respond to DNS queries on an alternative domain through the alt_domain agent configuration option. When performing an SRV query for this service, the SRV response contains a single record with a hostname in the format of .addr..consul. TXT records are useful for multiple types of records like DKIM, SPF, etc. You can find all TXT records configured for any domain using the below command. Click on the “Lookup Nameserver” button to get the nameservers of the entered domain name. The request will be sent to the nameservers mentioned above as per their priority to get the example.com A record. To solve the query and to get the nameservers of the example.com. So, in the network environment, the DNS server has a hostname for each device. When the DHCP server allocates an IP address to a device, it passes that information on to the DNS server, which updates its records for that hostname. Some applications use hostnames to identify the destination of their communications on the network. There are 13 root DNS servers in the world and every recursive server has all of its contact details. The root nameserver returns the address of a TLD nameserver (top-level domain) to contact.
