.citadel domain extension

.citadel is a generic top-level domain extension controlled by Citadel Domain LLC, a company based in Chicago, Illinois. The domain is operated on their behalf by Identity Digital, which handles the technical backend. There are no public eligibility restrictions listed in the IANA record. The registry website points to citadel.com, suggesting the TLD is primarily used to support the Citadel brand. Intended for internal or external brand-related use, .citadel gives the company a closed namespace on the internet. Registration services are available through their own portal, and the domain uses standard WHOIS and RDAP systems. IANA delegated .citadel to Citadel Domain LLC in July 2016, with the official registration date of June 30, 2016.
