Subdomain Finder (2024)

FAQs

Is there a way to find all subdomains? ›

Subdomains aren't inherently bad for SEO, but they can impact your site's SEO strategy if not used wisely. Since subdomains are treated as separate entities by search engines, they may dilute the overall authority of your main site if not managed properly.

There are several tools with dictionaries to check for possible takeovers: https://github.com/EdOverflow/can-i-take-over-xyz. https://github.com/blacklanternsecurity/bbot. https://github.com/punk-security/dnsReaper.

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.

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.

Yes, Google does index subdomains.

However, it's crucial to note that while Google indexes subdomains, each subdomain's ranking would still depend on the quality and relevance of its content, its inbound links, and several other SEO factors.

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.

Yes. When you purchase the root domain, you can set up any subdomain you want on that root domain. Before you use Google Search Console (used to be Google Webmaster Tool), you should set up your site so that all traffic going to the root domain gets redirected to the www version.

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.).

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.

Scraping (JS/Source Code): Scraping is the practice of extracting subdomains from source code and JavaScript files present on web pages using tools like httpx and gospider to facilitate this process. Professionals use such software to crawl websites in order to extract subdomains.

Subdomain takeover can have severe legal implications, as attackers may engage in illegal activities or host malicious content on compromised subdomains.

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.”

Subdomain spoofing

Attackers might also take advantage of subdomains by creating malicious sites that appear as if they are part of a larger, trusted domain. This can be particularly deceptive because the main part of the domain name remains unchanged.

Characteristics and Parameters of a Subdomain

A domain can have up to 500 subdomains. You can create multiple levels of subdomains such as store.product.yoursite.com, test.forum.yoursite.com, etc. Each subdomain can be up to 255 characters long, but for multi level subdomains, each level can only be 63 characters long.

To find all available pages on a specific domain using Google, simply enter "site.com" into the Google search bar. This search query will return a list of indexed pages from that domain, helping you quickly identify the available content. Find website pages on Google.

There are some subdomains that are defined for virtually every domain name, such as www, and others that are very common, like shop or mail. But by going through and trying a DNS query using `dig`, `nslookup`, or `host` for as many possible subdomains, you might find some hidden ones.

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.
