.comsec Domain — reserved extension, not available for public registration
.comsec was registered with IANA on 8 October 2015 and is managed by VeriSign, Inc., the same company that operates .com and .net. However, real registration data shows this extension was never commercially opened to the public: only one active domain exists, held by VeriSign itself as "Reserved - Registry Operator acts as Registrar."

About the .COMSEC domain
What is the .COMSEC domain?
Despite appearing as a delegated generic domain in IANA, .comsec is not actually open for public registration: according to available registration data, only a single domain exists under this extension, held by the registry operator itself (VeriSign, Inc.) as "Reserved." There is no real commercial availability for individuals or businesses.
Uses of .COMSEC
Who is the .COMSEC domain for?
These are the most common situations where .COMSEC is the ideal extension.
Reserved for use by the registry operator itself
The single existing domain under .comsec is held directly by VeriSign, with no sale to third parties.
Not available for public registration
Unlike the vast majority of generic extensions, .comsec does not accept registration requests from individuals or businesses through standard registrars.
Possible strategic reservation by the operator
Some registry operators maintain delegated extensions without an active commercial launch, reserving them for future use or their own brand protection.
Formal delegation without commercial activity
It is present in the IANA database as a delegated extension, but without the usual commercial ecosystem of registrars and resale.
Not suitable for commercial or personal projects
If you're looking to register a domain for your business or project, this extension is not currently an available option.

Frequently asked questions about the .COMSEC domain
Can I register a .comsec domain?
No. Although it is delegated in IANA and managed by VeriSign, Inc., registration data shows only a single domain exists, reserved by the operator itself. It is not commercially available to individuals or businesses.
Why does VeriSign have an extension it doesn't sell?
Some registry operators request and maintain delegated extensions without commercially launching them, whether for strategic reasons, brand reservation, or a possible unannounced future use.
Is this the same as a brand (.brand) extension?
Not exactly. .brand extensions follow ICANN's Specification 13 and are tied to a specific company for its own use. .comsec is a delegated generic extension but with no known commercial or public-use activity.
Who manages .comsec?
VeriSign, Inc., the same company that operates the .com and .net extensions. It was registered with IANA on 8 October 2015.
