IDN domains don't permit to mix different Scripts or character sets (for example, Latin, Greek or Cyrillic).
But it's possible to use different character tables for a same script.
- The Latin Script permits the use of characters of Latin-1 supplement, Latin Extended-A, Latin Extended-B, etc.. tables.
- The Greek Script permits to combine characters of the Greek, Greek Extended, etc.. tables, doesn't permit combine them with the normal latin characters (a-z), but permits the use of numbers or hyphens.
- Other script types have their own corresponding tables.
Residency requirements
The administrative, technic and/or billing contact has to be an individual, not a company.
Technical requirements
.SI domains require the DNS to be active on different subnets and to be authoritative for the domain at the time of registration. You can check if they pass these minimum requirements using our Zone Check tool.
Registrations
.si domain registrations are immediate.
Transfers
To complete .SI domain transfer, you'll need your current registrar to provide you the domain's AuthCode or EPP-Key to verify the ownership of the domain.
Transfers can take between 5 and 7 days to complete. Some registrars provide manual transfers allowing transfers to be completed on the same day, contact your current registrar to find out if they offer this service.
More information about .SI domain transfers
When the transfer ends, the expiration date doesn't change.
Renewals
The renewal of .SI domains is different than with other extensions.
It's necessary to request the domain renewal at least 33 days before the domain expiration.
In case the renewal request is done after this date, the correct renewal is not guaranteed.
Cancellations
It's possible to request a cancellation of your .SI domain, visit the support center to open a support ticket. Please note, cancelling a name does not provide a refund of any registration fees.
DNS modifications
DNS modification is immediate, please note they must propagate through the network, this process can take up to 6-12 hours to complete, until then the domain will still point to the previous DNS servers.
DNSSEC
We allow the usage of DNSSEC on .si domains. Your domain can take advantage of this additional security layer that DNS servers that are compatible with this technology can provide.
More information is available at: What is DNSSEC and how does it work
Domain owner change
Unfortunately it's not possible to make ownership changes in this type of domain names.
