Here are some common examples of the host
command in Linux and Unix:
- To perform a simple DNS lookup for a hostname, you can run the following command:
host example.com
- To perform a reverse DNS lookup for an IP address, you can run the following command:
host 8.8.8.8
- You can also specify the DNS server to use for the lookup by using the
-t
option:
host -t MX example.com 8.8.8.8
- To perform a verbose lookup, which includes all the resource records associated with a domain, you can use the
-v
option:
host -v example.com
- You can also specify the type of resource record you want to retrieve using the
-t
option:
host -t A example.com
