|
|
|
- Lookup the IP(s) associated with a hostname (A records):
|
|
|
|
`dig +short {{example.com}}`
|
|
|
|
- Get a detailed answer for a given domain (A records):
|
|
|
|
`dig +noall +answer {{example.com}}`
|
|
|
|
- Query a specific DNS record type associated with a given domain name:
|
|
|
|
`dig +short {{example.com}} {{A|MX|TXT|CNAME|NS}}`
|
|
|
|
- Specify an alternate DNS server to query:
|
|
|
|
`dig @{{8.8.8.8}} {{example.com}}`
|
|
|
|
- Perform a reverse DNS lookup on an IP address (PTR record):
|
|
|
|
`dig -x {{8.8.8.8}}`
|
|
|
|
- Find authoritative name servers for the zone and display SOA records:
|
|
|
|
`dig +nssearch {{example.com}}`
|
|
|
|
- Perform iterative queries and display the entire trace path to resolve a domain name:
|
|
|
|
`dig +trace {{example.com}}`
|
|
|
|
- Query a DNS server over a non-standard [p]ort using the TCP protocol:
|
|
|
|
`dig +tcp -p {{port}} @{{dns_server_ip}} {{example.com}}`
