Improve Article Save Article host command in Linux system is used for DNS (Domain Name System) lookup operations. In simple words, this command is used to find the IP address of a particular domain name or if you want to find out the domain name of a particular IP address the host command becomes handy. You can also find more specific details of a domain by specifying the corresponding option along with the domain name. Syntax: host [-aCdlriTWV] [-c class] [-N ndots] [-t type] [-W time]
[-R number] [-m flag] hostname [server]
host command without any option: It will print the general syntax of the command along with the various options that can be used with the host command as well as gives a brief description about each option. Example:  Different options with the host command:
The solutions given so far mostly work in the simpler case: the hostname directly resolves to a single IPv4 address. This might be the only case where you need to resolve hostnames, but if not, below is a discussion on some cases that you might need to handle. Chris Down and Heinzi briefly discussed the case where the hostname resolves to more than one IP addresses. In this case (and others below), basic scripting under the assumption that a hostname directly resolves to a single IP address may break. Below, an example with a hostname resolving to more than a single IP address: But what is So But can aliases be chained? The answer is yes: I did not find any example where a hostname resolves to an alias that does not resolve to an IP address, but I think the case might occur. More than multiple IP addresses and aliases, is there some other special cases... what about IPv6? You could try: Where the hostname Again about IPv6, if your host is IPv4 only, you can still resolve IPv6 addresses (tested on a IPv4 only WinXP and with ipv6.google.com, you could try it on Linux). In this case, the resolution succeeds, but a ping fails with an unknown host error message. This might be a case where your scripting fails. I hope those remarks were useful. What resolves domain names to IP addresses?DNS servers convert URLs and domain names into IP addresses that computers can understand and use. They translate what a user types into a browser into something the machine can use to find a webpage. This process of translation and lookup is called DNS resolution.
Which of the following commands can be used to resolve a DNS name to an IP address?The Nslookup command is available on many of the popular computer operating systems like Windows, macOS, and Linux distros. You can use it to perform DNS queries and receive: domain names or IP addresses, or any other specific DNS Records.
