Subdomain &
Shadow IT
Intelligence

Engineered by the specialists at ARPSyndicate

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 100 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.
