Subdomain Center scours the web, gathering and interpreting data from from all over the Internet. Consequently, it has evolved into
The World's Largest Subdomain & Shadow IT Intelligence Database and is freely accessible to all.
To avoid abuse of this service, we have enforced
aggressive rate-limits & a maximum of 500 subdomains per request sorted in a random order.
During periods of high demand or extensive production,
an empty list `[]` is returned. We do not take responsibility for any malicious use of our data, and such use is entirely unintended.
We apologize in advance for any unexpected downtime & delays.
Our servers are often caught in a tug-of-war between an army of demanding users and a potato-powered
hamster.
