Subdomain Lookup (2024)

FAQs

Is there a way to find all subdomains? ›

While subdomains can work well for some companies, depending on their goals, a subdirectory is often a better choice for SEO.

It's a cyber threat executed when an attacker gains control of a legitimate subdomain that's no longer in use, then cleverly exploits the forgotten or misconfigured dangling DNS to host their own content on the previously used zone.

Subdomain Finder scans the DNS records and supplementary databases to analyze the domain's hierarchy. Our subdomain scanner checks: DNS records (NS, MX, TXT, AXFR) DNS enumeration. SSL certificates.

The short answer is yes, Google can and will index and rank subdomains unless you explicitly take steps to ensure they're excluded from its index. Google's entire business model is based on discovering content. The same goes for all search engines.

In general, subdomains can rank well on Google if they have high-quality content that is relevant to the user's search query. However, subdomains may have less authority than the main domain, which can make it harder for them to rank for competitive keywords.

One of the disadvantages of opting for the subdomain option is that because the search engines view them as separate sites, they are treated as separate domains when it comes to determining rankings. Considerations need to be made for developing a subdomain into its own entity.

To identify DNS entries within your organization that might be dangling, use Microsoft's GitHub-hosted PowerShell tools "Get-DanglingDnsRecords". This tool helps Azure customers list all domains with a CNAME associated to an existing Azure resource that was created on their subscriptions or tenants.

What is subdomain stripping? ›

Subdomain stripping is the process of removing the subdomains from the main domain and delivering the emails to the main domain directly.

you can verify your subdomain to be used in Google Search Console by linking your account to Google Analytics. This way you avoid customizing the theme of your help center. Go to www.google.com/analytics and set up a property within your Google Analytics account for your subdomain.

Subdomain takeover can have severe legal implications, as attackers may engage in illegal activities or host malicious content on compromised subdomains. It's crucial to report any such incidents to law enforcement authorities and take immediate steps to mitigate the risks to protect your reputation and users.

A subdomain takeover occurs when an attacker gains control over a subdomain of a target domain. Typically, this happens when the subdomain has a canonical name (CNAME) in the Domain Name System (DNS), but no host is providing content for it.

Google Considers Subdomains as Separate Standalone Sites

“You'll need to verify subdomains separately in Search Console, make any changes to settings and track overall performance per subdomain. We do have to learn how to crawl them separately but for the most part that's just a formality for the first few days.”

If all else fails, you can use Google search to find all the pages on a website. Simply type “site:example.com” (replace “example.com” with the website's URL) into Google's search bar, and it will return a list of all the pages on that site that Google has indexed.

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.

Using nslookup online is very simple. Enter a domain name in the search bar above and hit 'enter'. This will take you to an overview of DNS records for the domain name you specified.

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.
