Defensive registrations do not resolve in the DNS, but do block others from registering the same name. Spaces in a trademark may be replaced with a hyphen ("-") or removed to form a continuous string. For help in converting other characters, such as "&", please read this

Defensive Registrations must be associated with a trademark held by the registrant.

The registered trademark can be from ANY national trademark register. All defensive registrations have a term of four years.

Fields in BOLD indicate required fields.


Registrants may request to convert any defensive registration to a regular resolving name. Conversion requests will only be processed at the beginning of the live registry period. All conversion requests must be accompanied by Professional Eligibility data.

Conversion requests are made separately from the Defensive registration by using the ProReserve application form.
