Use dig si

It seems like you're asking about the `dig` command, which is a tool used to query Domain Name System (DNS) servers to retrieve information about various types of DNS records. The term "si" is unclear; if you meant to refer to a specific function or option, please provide more details. Here's a basic example of how to use the `dig` command: ### Basic Usage To perform a simple DNS lookup: ```bash dig example.com ``` This command retrieves the A record (the IP address) for `example.com`. ### Specifying Record Types You can specify different record types using the `IN` and record type flags: ```bash dig example.com A # A record (IP address) dig example.com MX # Mail exchange record dig example.com CNAME # Canonical name record dig example.com NS # Name server record ``` ### Using a Specific DNS Server If you want to query a specific DNS server, you can specify the server's IP address or domain: ```bash dig @8.8.8.8 example.com # Using Google’s public DNS server ``` ### Getting Additional Information You can add the `+short` option for a more concise output: ```bash dig +short example.com ``` ### Example Query with Additional Options To perform a query and see additional details: ```bash dig +nostats +noquestion +nocmd example.com ``` This command suppresses some output for clarity. ### Reverse Lookup To perform a reverse DNS lookup (finding the domain name associated with an IP address): ```bash dig -x 93.184.216.34 # Replace with an actual IP address ``` ### Conclusion The `dig` command is quite versatile and powerful for managing DNS queries. If the mention of "si" was meant to refer to a specific domain or functionality, please clarify, and I’d be happy to provide further details!
