How to test an Edge DNS zone processing

You can test your zones to check if they're properly processing information.

Once you’ve set up your Edge DNS zone, you can test it to see if it’s properly processing your information.

Using the DIG command

Domain Information Groper (DIG) is a network administration command-line tool. It’s useful for network troubleshooting and for educational purposes. When a specific nameserver isn’t specified in the command invocation, it uses the operating system’s default resolver, usually configured in the file resolv.conf. Without any arguments, it queries the DNS root zone.

To test Edge DNS, you must use one of the Azion nameservers that you’ve configured in your DNS registry.

Using the HOST command

Host queries the DNS, converting domain names into IP addresses and vice-versa. If no argument or option is provided, the host prints a brief summary of the command line options and arguments.

For example, if you have the following settings:

Name	Type	Value	TTL
www	A	192.168.0.1 192.168.0.2 192.168.0.3	3600

To check how Edge DNS handles a type A query, registered to the www record, run:

host www.example.com ns1.aziondns.net

The response to this will be:

Using domain server: Name: ns1.aziondns.net Address: 179.191.160.2#53 Aliases: www.example.com has address 192.168.0.1 www.example.com has address 192.168.0.2 www.example.com has address 192.168.0.3

Using the NSLOOKUP command

nslookup is a tool used to obtain information about DNS records for a particular domain, host, or IP.

For example, if you have the following settings:

Name	Type	Value	TTL
www	A	192.168.0.1 192.168.0.2 192.168.0.3	3600

To check how Edge DNS handles a type A query, registered to the www record, run the following command:

nslookup www.example.com ns1.aziondns.net

The response to this will be:

Server: ns1.aziondns.net Address: 179.191.160.2#53 Name: www.example.com Address: 192.168.0.1 Name: www.example.com Address: 192.168.0.2 Name: www.example.com Address: 192.168.0.3
