About DomainLimits

DomainLimits (domainlimits.com) is an independent, free website that explains the practical rules of owning domain names: how long a name can be, which characters are allowed, whether there is a limit on how many domains you can register, how registrars and TLDs differ, and what happens when a domain expires.

Who it is for

Small-business owners registering their first domain, developers managing several projects, and hobbyists building a small portfolio who want straightforward answers without a sales pitch.

What is on the site

• Domain limits overview – name length and label limits, per-account registrar limits and subdomain limits on popular platforms.
• Registrar comparison and domain search tips for choosing a registrar and a name.
• Hosting guide explaining shared, VPS, dedicated and cloud hosting for a new domain.

What DomainLimits is not

We do not sell domains, hosting or brokerage services, and the site has no accounts or paid plans. We are not affiliated with ICANN or with any registrar we write about. For subdomain set-up guides, see our sister reference subdoms.com.

How the site is run

The site is maintained independently as a static website and is supported by advertising (Google AdSense). Prices and policies in the domain industry change frequently, so pages are reviewed and updated over time; corrections are welcome through the contact page.
