resolveip is a command-line utility that resolves hostnames to their corresponding IP addresses, and vice versa. It is often used to troubleshoot network connectivity issues or to configure network settings on a Linux system.
Here are some of the main features of resolveip:
- Resolve hostnames to IP addresses: resolveip can be used to convert a hostname to its corresponding IP address. This is useful when you need to connect to a remote system or service using its IP address.
- Resolve IP addresses to hostnames: resolveip can also be used to convert an IP address to its corresponding hostname. This is useful when you need to identify the hostname of a remote system or service.
- Resolve multiple addresses: resolveip can resolve multiple hostnames or IP addresses at once. This can save time when you need to resolve a large number of addresses.
- Support for IPv6: resolveip supports both IPv4 and IPv6 addresses. This makes it useful for resolving addresses on modern networks that use IPv6.
resolveip Command Examples
1. Resolve a hostname to an IP address:
# resolveip example.org
2. Resolve an IP address to a hostname:
# resolveip 22.214.171.124
3. Silent mode. Produces less output:
# resolveip --silent example.org
In addition to these features, resolveip can also be used in conjunction with other tools, such as ping and traceroute, to troubleshoot network connectivity issues. For example, you can use resolveip to determine the IP address of a remote system, and then use ping to test the network connection to that system.
Overall, resolveip is a versatile tool that can be used to resolve hostnames and IP addresses, and is particularly useful for network administrators and developers who need to troubleshoot network connectivity issues on a Linux system.
