About .srt domains

About .srt domains

.SRT is a generic top-level domain (gTLD) delegated in the DNS root zone. The registry operator responsible for .SRT is listed by IANA as the contracted registry operator. Anyone can typically register a .SRT name through an accredited registrar, subject to the registry’s registration policy and ICANN consensus policies.

SubRip is a free software program for Microsoft Windows which extracts subtitles and their timings from various video formats to a text file. It is released under the GNU GPL. Its subtitle format's file extension is .srt and is widely supported. Each .srt file is a human-readable file format where the subtitles are stored sequentially along with the timing information. Most subtitles distributed on the Internet are in this format.

Who can register .srt domains?

Eligibility is defined by the registry operator and its registrars. Most gTLDs are open to anyone worldwide. Many ccTLDs are also open globally; some require local presence, citizenship, or trademark rights. Always confirm current policy with the registry or your registrar.
