Querying DNS Records with DIG (Domain Information Groper) #

dig is a powerful command-line tool used by network administrators and webmasters to query Domain Name System (DNS) servers and verify DNS record propagation, TTL values, and name server responses.

Basic Syntax: #

dig [options] domain.com [record_type]

1. Common DIG Command Examples: #

Query Standard A Record:
```
dig example.com
```

Query Specific Record Types (MX, TXT, CNAME, NS, SOA):

dig example.com MX
dig example.com TXT
dig example.com NS

Query a Specific DNS Server (e.g., Google 8.8.8.8 or Cloudflare 1.1.1.1):
```
dig @8.8.8.8 example.com
```
Short Clean Output (Returns only the IP):
```
dig +short example.com
```
Trace Full DNS Delegation Path from Root:
```
dig +trace example.com
```

Tip: dig +trace is especially useful when verifying newly configured Tarweig nameservers, as it inspects the exact delegation from root and TLD servers down to your authoritative zone.
