Which of the following commands is used to look up DNS records for a remote host?

The `find` command is not related to DNS lookups; it is primarily used in Unix-like systems to search for files and directories within the file system. It does not have the capability to query DNS records or provide information about remote hosts.

While `curl` is a tool for transferring data from or to a server using various protocols (including HTTP and FTP), it does not directly query DNS records. It can resolve hostnames to IP addresses, but its primary function is not DNS lookup, making it unsuitable for this specific task.

The `ip` command is used for network configuration and management tasks, such as displaying and manipulating routing, devices, policy routing, and tunnels. It is not designed for querying DNS records and therefore does not serve the purpose of looking up information about remote hosts via DNS.
