Estimates rounded from our own WHOIS observations. Figures count domains registered, not domains held. Last measured September 2026.
How many domains does IONOS register?
About 140k a month, which is 1.5% of every domain registered anywhere. That counts new registrations rather than the domains it holds, which is a much larger number and one no public data source measures directly.
Is IONOS growing?
Its share of new registrations has risen by 0.3 percentage points against the same months of last year, to 1.5%. Share is the useful measure here: the whole market grew, so a registrar can register more domains than last year and still be losing ground.
How many domain extensions does IONOS sell?
It registered domains across 324 extensions this year. 47.5% of what it sells is .com.
What is IONOS strongest at?
.store. It handles 13% of everything registered under that extension, 7.3 times its 1.5% share of the market overall. That ratio is the useful one: it shows where a registrar is unusually strong rather than simply where it sells the most.
What kind of names do people register at IONOS?
The average is 13 characters, 5% contain a digit and 16.5% contain a hyphen. A high digit share indicates bulk registration rather than names someone sat down and chose, so this is the closest thing to a read on who a registrar's customers actually are.
Do people register with IONOS for more than one year?
3% do, against 97% who take a single year. Multi-year registrations are a minority almost everywhere, so the differences between registrars are large in relative terms.
Where do IONOS domains point their DNS?
22.5% use ui-dns.org. About 0.5% of them sit on a parking or for-sale page rather than a working site. Measured across 2025, the last period for which nameserver data is complete.
When do IONOS domains come up for renewal?
March 2027 is the busiest month ahead, with about 370k reaching their renewal date. Renewal peaks trail registration peaks by exactly a year, so whatever is not renewed then becomes available again.
Can anyone register a domain with IONOS?
Yes. IONOS is an ICANN-accredited registrar, IANA ID 83, and sells directly to the public with no membership or eligibility requirement.
Can I transfer a domain away from IONOS?
Yes. A domain can be transferred to another registrar sixty days after it is registered or last transferred, which is an ICANN rule rather than a registrar policy. You need the authorisation code from your current registrar and the domain must not be locked.
