When a New gTLD represents a community, whether it be geographical, or socially based, oftentimes there are special considerations for members of that group. One of these may come in the form of a special sunrise registration conducted prior to public registration launch to protect the interests of community members and to encourage their adoption and use of their domain names within their internet strategies.
In the case of geographical and city based TLDs it could be something like SunsetTan.Vegas, or SandysHotSnacks.Vegas. Any local establishment could apply to see if their names could be qualified and registered.
.SALON may decide to give brick and mortar salon businesses first crach at their business names.
Other communities could have different criteria for special consideration. In the case of .MUSIC it has been suggested that bands, and artists who can demonstrate use of their name will be able to register and use that .MUSIC domain name.
The qualifications and requirements can vary by the specific extension to suit the vision and needs of that tld registry.
Every ctld that could concievably represent a community will not offer this. And, those that do will have wide ranging requirements for registration.
It’s important to be informed about the specific tlds you care about.
