Purpose of IP address and domain name?

Answer 1

Think of it as your street address on the internet.

For example, when a public edit is made on a Wikipedia page, your public IP address is listed. If you vandalize and screw up several pages, they use that address to block your edits from happening again.

A similar case is used in omegle.com's video feature. Your public IP address is associated with your computer. If the website detects a bad reputation (ex. indecent exposure), your IP will not be permitted to access that site.

Answer 2

An IP address, much like your phone number, is a way to find a specific server or computer on the internet, or a network.

A domain name is used to 'mask' this IP address, by typing an easy to remember, user-friendly 'domain' such as www.Google.com, as opposed to 208.69.36.231

Additionally, a DNS Server (Domain/Dynamic Name Service) is a server that your computer knows by IP address, and asks to 'find' the IP address of a website.

Computers do not actually know how to load a website without the IP address. So even though you may tell it www.google.com, it must first ask the DNS (usually your router, or ISP) what www.google.com's IP address it.

Once the DNS Server respond with the IP address, your computer will negotiate a connection to the website. If the webserver accepts, it will begin sending your computer the page.

Your computer then parses the HTML or other website code, and displays the website for you.

If your DNS server is down, this can cause some things (games, Instant messengers) to work fine, but webpages not to.
