What is the maximum length limit of a domain name? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.
The maximum length of a domain name is 63 characters, while the total length of a domain name cannot exceed 253 characters. There is no case distinction in a domain name.
The domain name has the international top-level domain name and the national top-level domain name, the general top-level domain name, altogether has 8, namely now commonly called the international domain name. Geographical top-level domain name, a total of 243 country and region codes, such as .CN for China, .UK for the United Kingdom. The registration authority of each domain name is different, which also leads to a deviation in the registration rules of each domain name. But there are also common basic principles:
1. It can contain English letters (26 amurzgrates), numbers (10 from 0 to 9), and the half-corner hyphen "-" (middle hyphen). Spaces and special characters cannot be used (such as! , $, &,? Etc.)
2. "-" cannot appear continuously, cannot be registered separately, and cannot be placed at the beginning or end.
3. The length of the domain name is limited, and a maximum of 63 characters can be registered.
4. In the domain name, the case of English letters is not distinguished.
The length limit of the domain name here is what every domain name needs to follow. In general, the shorter the length of a domain name, the higher its value. Of course, some domain names are long, but the meaning is good, and the value of their domain names is not low.
