Start monitoring freeHow to read your domain expiry result
The expiry date is when your domain registration runs out - not the certificate. If it lapses the domain can stop resolving and, after a grace period, be registered by someone else. The result shows the date, the days remaining and the registrar of record, read live from the registry via RDAP.
Domain expiry is one of the quietest ways for a business to lose its website and email at once, because the renewal notice often lands in an inbox nobody watches. A one-off check tells you where you stand today; continuous monitoring warns you 30, 14, 7, 3 and 1 day ahead so a renewal never slips through.
About domain expiry
What is domain expiry?
Every domain is registered for a period and must be renewed before it expires. If it lapses, your website and email stop working and someone else can grab the name.
Why monitor domain expiry?
Renewal emails get missed, cards expire, people leave the company. An automatic watch on the registration date is the cheapest insurance against losing your domain.
What are RDAP and WHOIS?
RDAP and WHOIS are the registry protocols that publish domain registration data, including the expiry date. WWT uses RDAP with a WHOIS fallback.
What is RDAP, and why use it instead of WHOIS?
RDAP is the modern, structured successor to WHOIS. It returns machine-readable registration data straight from the registry, which is more reliable than parsing free-text WHOIS. For the few TLDs without RDAP, a manual override is available.
My TLD shows no data - what does that mean?
Some country-code registries publish no RDAP endpoint, so an automated lookup cannot read the expiry date. That is not a fault on your side - in the full product you can set the renewal date manually and still receive expiry alerts.
