Some TLDs (such as .fi, .es, .nu, .xxx) require additional details for their registration. Some of the details the registry asks can be:

  • company registration number
  • vat registration number
  • personal ID number (such as passport number)

What is DNS?

DNS stands for Domain Name System that translates the IP addresses into domain names, so the users do not need to know the IP address. Please find here more information: DNS

Leaseweb nameservers information

If you wish to use the Leaseweb DNS, please use the authoritive nameservers below:

Please find more nameservers details in the Cheat Sheet article.


By default, all new domains will use Leaseweb name servers. With a transfer of domain, the name servers will not be changed. It is required to request a change explicitly at This also applies for glue records.

DNS record types

At Leaseweb, DNS records can be set by you for each domain using the Leaseweb Customer Portal. To know more about the most used DNS record types, please visit: DNS records types.

Time to Live (TTL) and DNS caching

Time to Live (TTL) is used to renew the DNS records on all the DNS servers around the world to the set TTL value. 

The units used are seconds. The older common TTL value for DNS was 86400 seconds, which is 24 hours. A TTL value of 86400 would mean that, if a DNS record was changed on the authoritative name server, the DNS servers around the world could still be showing the old value from their cache for up to 24 hours after the change.

Why change the TTL value


If you change the TTL, you have to wait for the current TTL to pass before the new TTL will be active. This means that if you change the TTL to 1 hour instead of 24 hours, you have to wait the 24 hours first before the 1 hour TTL will be active.

Setting a TTL value lower than 12 hours is not recommended, and should only be used during a short period for special cases. By default, the TTL value is 24 hours.

Anonymous domain registrations (WHOIS privacy)

The WHOIS Privacy service is intended to protect the registrant’s WHOIS information for legitimate purposes.

This is an additional service that Leaseweb provides for some top level domain names. For detailed information, please visit: WHOIS Privacy Service for Domain.

When I add a DNS record I receive the error: Sorry, the application encountered an unknown error.

When you have received the error while adding a MX, A or TXT record. The error is very likely caused by an existing CNAME record. It is not allowed to have duplicate CNAME, TXT, MX and A record in your zone. More information about this RFC can found in the LINK.

ICANN contact verification

ICANN (Internet Corporation for Assigned Names and Numbers) is an internationally organized, non-profit corporation that has responsibility for Internet Protocol (IP) address space allocation, protocol identifier assignment, generic (gTLD) and country code (ccTLD) Top-Level Domain name system management, and root server system management functions.

As part of the ongoing effort to improve contact quality, ICANN requires contact validation for each domain owner contact registering a domain name or changing the domain owner email address. In these situations, the domain name owner will receive an email directly from ICANN to confirm the contact details. The domain name owner will need to confirm the link in order to validate that the contact details are correct. The email validation is a one-time process.


Please make sure to follow the ICANN Contact Verification email instructions within 14 days since the notification receipt. Your domain will be set on “client/server hold” status by the registry if the email is not validated on time.

Web Hosting packages offer the option of adding domain aliases via Plesk. When you add a domain as an alias, it gets linked to an existing website. This newly added domain then appears as the main website.
