See Subdomains Of A Domain (2024)

FAQs

How do I see all subdomains of a domain? ›

Using a terminal and the command nslookup is the most effective way to search a domain's DNS records. On almost all operating systems, this command works perfectly and displays all DNS records for the domain. To show how to use the command, here's a sample nslookup command for each record type.

Find Subdomains of a Domain with NsLookup:

Replace “example.com” with the domain name you are interested in. This command will return a list of the authoritative name servers for the domain, which can often include the subdomains.

Each domain name can have up to 500 subdomains. You can also add multiple levels of subdomains, such as info.blog.yoursite.com. A subdomain can be up to 255 characters long, but if you have multiple levels in your subdomain, each level can only be 63 characters long.

Your subdomain reputation(s) can impact base domain reputation, but the impact between subdomains will be small. Subdomains are not a way to avoid a bad domain reputation. Instead, they will help differentiate your traffic while maintaining a clear relationship with your main domain.

However, Google treats subdomains as separate sites.

While “blog.example.com” and “example.com” may share a root domain, Googlebot will view them as distinct domains and crawl and index them accordingly.

A CNAME record is an alias for a subdomain. When you configure a CNAME record for a subdomain, DNS queries are no longer sent for the subdomain but for the domain or subdomain specified in the CNAME record to the appropriate name server.

Online nslookup is a web based DNS client that queries DNS records for a given domain name. It allows you to view all the DNS records for a website. It provides the same information as command line tools like dig and nslookup, from the convenience of your web browser.

By default, the domain and its subdomains are part of the same DNS zone, i.e. they are hosted on the same web server. You also have the ability to create a delegation, in order to redirect one or more subdomains on another server.

What is subdomain lookup? ›

A Subdomain Finder is a subdomain enumeration tool that helps you discover subdomain hosts (aka subdomain FQDNs) which serve specific functions for your target (e.g. hosting public websites, private subdomains for testing web apps, URLs where you can find backups, etc.).

You can usually locate it in the root or footer section of the website. For example, the XML sitemap URL could be “www.example.com/sitemap.xml“. Once you click on the sitemap, you will find all pages & subpages of a website. You can use different sitemap generation tools if you don't have an existing sitemap.

A hostname can consist of many sub-domains. For example, www.motorace.blogspot.google.com. In theory, a hostname could include 126 levels of subdomain.

The choice between subdomains and subdirectories largely depends on reasons outside of SEO. Both can be SEO-friendly. Whether you decide to use subdomains or subdirectories, you need to optimize them for the best chance of ranking in search engines.

Google Dorking

Google Dorks are one of the best ways to find extenstive information about a target. Google's search operators make it easy to narrow down the search to find more subdomains. We can use the "site" operator in the search bar to find all the subdomains that Google has indexed for a domain.

Subdomains are used to expand the use of a single domain, these do not need to be purchased separately to your domain; if you own a domain then you can add a subdomain to this. This method is commonly used for Moodle and Totara site setups.
