What are top-level domains (TLD) and country code top-level domains (ccTLD)?
Each domain name has different pieces that are part of the domain name system hierarchy. The different pieces are identified by where they are in relation to the dot ( . ), whether it is to the right or to the left.
A Top Level Domain (TLD) is the part of the domain name located to the right of the dot (" . "). The most common TLDs are .com, .net, .org, and .gov. Some others are .info, .biz, .mil, .me, and .africa domains. These common TLDs all have certain guidelines, but are always available to any registrant, anywhere around the globe.
There are also restricted top-level domains (rTLDs), like .edu, .school, .me, etc, that authorize the registrant to showcase a certain type of entity, or to belong to a certain community. For example, the .me TLD is reserved for individuals, and .edu is reserved for educational entities.
Country-code TLDs (ccTLDs) stands for specific geographic locations. For example: .co.ke represents Kenya and .ug represents the Uganda. Some ccTLDs have residency curtailment. For example, .co.ke or .ke requires registrants to live in Kenya. Other ccTLDs, like the ccTLD .tz representing Tanzania, allow anyone to register them, but require a trustee service if the registrant is not located in a specified country or region.
Lastly, there are ccTLDs that can be registered by anyone — .co representing Colombia, for example, has no residency requirements at all.
The bit of the domain name to the left of the dot, before the TLD, is the Second Level Domain. This is the slice of your domain that is distinctive to you and your brand, and your options are nearly unlimited. For example, in sinosoft.guru, sinosoft would be the SLD (Second Level Domain).
Now that you know the types of domains and their differences, you can register a new domain
