# What is a subdomain?

| What is a subdomain?
---
**Subdomains** are extensions of your domain name that you can forward to URLs or point to IP addresses and directories within your hosting account.

It’s easy to create a memorable Web address for unique content areas of your site by using subdomains.

For example, you could create a subdomain for pictures on your site called "pics" that is accessible through the URL **pics.wallpaperexample.com** in addition to **www.wallpaperexample.com/pics**.

You can add up to 100 subdomains per domain name.
You can also add multiple levels of **subdomains**.
For instance, you can add **info.blog.wallpaperexample.com** to delve into an even more specific area of interest on your site. Each subdomain can be up to 25 characters long.
