Subdomain
« เมื่อ: มิถุนายน 04, 2021, 22:13:33 »
Subdomains are the third level of a domain's hierarchy and are parts of a larger top-level domain. They are added in front of the root domain and separated from the domain name with a period.รูเล็ตออนไลน์


For example, "blog.example.com" and "english.example.com" are both subdomains of the "example.com" root domain. Subdomains are free to create under any root domain that a webmaster controls.

The two most common subdomain choices are:

http://www.example.com ("www" is the subdomain)
http://example.com (has no subdomain)
These are also the subdomains that commonly result in canonicalization errors.
