TLD
Top-Level Domain—the suffix at the end of domain names like .com, .org, .io, or country codes like .uk. Different TLDs carry different connotations and trust levels. Choose TLDs appropriate for your audience and purpose.
Subdomain
Publishing
A prefix before the main domain name creating separate sections, like blog.example.com or shop.example.com. Subdomains can isolate different applications while maintaining brand association. Consider whether subdomains or subdirectories better serve your SEO strategy.
AAAA Record
Publishing
A DNS record that maps a hostname to an IPv6 address. It is the IPv6 equivalent of an A record and is used when your domain should resolve directly to an IPv6 endpoint.
