Question A domain's DNS can't find it's own hosts / A record?

[lantis3]

Isn't a domain name's registered DNS supposed to have records of its own hosts like "A" record?

Why nslookup command always tell me it can't find the record or there is no response from the dns server?

And these dns servers are supposed to be autoreactive dns servers, right?

C:\Windows\System32>nslookup -type=ns tomshardware.com
Server:  dns.google
Address:  8.8.8.8

tomshardware.com        nameserver = ns-185.awsdns-23.com
tomshardware.com        nameserver = ns-840.awsdns-41.net
