GoDaddy is one website that checks the availability of domain names online. One can sign up on this website and they will inform you whether a domain name is available.
Domain name lookup lets you see whether a particular website name (the domain) has already been bought by someone. If so, it shows you who is the registered owner of that particular website name (the domain), their address, and until when they own it.
Most website builders will have them built right into their own website for when you go to register a domain name. From there they will let you know if it is available.
Reverse DNS lookup means one is trying to find the domain name associated with a particular IP address. Forward DNS lookup means one is trying to find the IP address associated with a domain name.

To find out who your domain name register is, use a "whois" service. For example go to whois.net and enter the domain name you want to lookup (without the www). You should then see a record with various details including who the registrar is.
A website domain is traditionally known as the name or URL of a website

Ip domain lookup command used for forward lookup and reverse lookup to be done in router.to resolve name to ip - forward look up and ip to name - reverse look up..

You need both for online presence of your business. Domain name is just like the address/location of your business on the web. When we type your domain name on our browser, it goes to your website. Website is more of a group of files that you show to your online visitors. You have a domain name but no website - what's the purpose of having your domain name? You have a website but no domain name - how can people see your website? The two things need to go together for online presence of your business.
Usually the person or company who purchased the domain name that is used to access the website. Without a domain name a website is not accessible from the internet. You can also specify who the owner is when purchasing the domain name.
A domain host functions as a host for your website. For example if you want a website for your company, you will require a domain host in order to set up a domain for your website. Often you can purchase a domain name that matches the name of your company.
The names of some of the domain name finding tools are web sites named WhoIs and Bust-A-Name. The popular domain company GoDaddy also has a lookup tool on their site.
