Registrar
The company that sold the domain. Transfer policies and renewal pricing vary by registrar, and that matters more than people think.
WHOIS Lookup
The full registration record for any domain: registrar, expiry, nameservers, and registry-level status flags. Plus whether it has sold publicly, is listed somewhere right now, or is heading toward expiry.
What is WHOIS?
WHOIS is the public record for a domain. It tells you who registered it, when, when it expires, and where DNS is pointed. Each TLD has its own registry that keeps the data (Verisign runs .com, PIR runs .org, and so on); we read the live record from those registries on every lookup.
Registration date
How old the domain is. Older names often have SEO value built up through years of backlinks.
Expiration date
When the current registration ends. If nobody renews, the domain enters a 60-day pre-drop window before going back on the market.
Nameservers
The DNS host the domain points at, usually a registrar default or a hosting provider. Tells you where the site (if any) actually lives.
Status flags
Registry-level locks like transfer-prohibited, pending-delete, redemption-period. The flags drop hunters watch when timing a backorder.
Last updated
When the registry last saw a change to the record. Useful for confirming a recent transfer or DNS migration actually went through.
