This service is intended only for query-based access. You agree that you will use this data only for lawful purposes and that, under no circumstances will you use this data to (a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the data recipient's own existing customers; or (b) enable high volume, automated, electronic processes that send queries or data to the systems of Identity Digital, a Registrar, or Registry Operator except as reasonably necessary to register domain names or modify existing registrations.

RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access.

About Substack

A domain that resolves to a newsletter platform belongs to a publisher who decided to own the address. Substack runs the publication behind it, and a site in this group has taken the step of mapping a domain of its own onto hosted infrastructure instead of publishing under the platform's subdomain, which is a small commitment but a real one and a useful filter.

The platform combines writing, email delivery, payments and subscriber management in one product, which is why the record files it under Blogs even though a reader experiences it as a website. Substack Inc. has operated the service since 2017 and it is Proprietary, with no self hosted edition, so every detection is a tenant rather than an installation. The publisher owns the audience and the domain name and rents everything underneath.

As of October 2026 we record Substack on 5,604 domains. The count covers domains rather than writers, which cuts in both directions: publications that never left a platform subdomain are missing entirely, while a publication that mapped several domains can appear more than once.

Media analysts use the population to measure how far independent publishing has consolidated onto one company's stack, a question that matters to anyone thinking about where audience relationships actually live. Advertising and sponsorship networks use it to find publications addressable at their own domain, which is the practical precondition for most direct deals. Vendors selling to writers, from payment and analytics tools to audience products, use it as a qualified prospect list, since paying to attach a custom domain is a rough but effective filter for a publication being run as a business rather than as a hobby.

The limits deserve a plain statement. Detection relies on markup and hosting signals the platform emits, and a publication placed behind a proxy or an unusual front end can pass unrecognized, so the total is a floor. Nothing in a row tells you audience size, subscription revenue or whether anybody still writes there, and a domain routinely outlives the publishing on it.

What an extract gives you that a lookup cannot is the whole set at once, ready to be joined against your own records, filtered by country or domain suffix, checked against the other technologies on the same domains, and compared with a previous release to see whether the platform is gaining domains or shedding them.
