FAQ
What are the parts of a domain name?
A domain consists of: subdomain (www, api), second-level domain (example), and top-level domain or TLD (.com, .org). Together they form the full domain like www.example.com.
What is a public suffix?
A public suffix is a domain under which Internet users can register names. Examples include .com, .co.uk, and .github.io. The registrable domain is directly under the public suffix.
Why is domain parsing useful?
Domain parsing helps with cookie scoping, security policies, URL normalization, analytics, and understanding the structure of web addresses for categorization or filtering.
