To ping a DNS domain, you would use the nslookup command. For example, to ping the domain example.com, you would use the following command:
nslookup example.com
If the domain is up, the command should return a response like the following:
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 9 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;example.com ANSWER SECTION: example.com. 86400 IN A 192. 168.1. If the domain is down, the command will return an error message like the following: ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;example. In this example, the domain example.com is not up. [related-posts id="55434, 55676, 54998, 55884"]
