Markdown Editor
Write Markdown and see it as you type, with GitHub alerts, tables, tasks, math, Mermaid and PlantUML.
Type a domain, an IP address or an AS number to see who it is registered to, asked of the registry that keeps it.

That's not a domain, an IP address or an AS number.
Domains are answered over RDAP, the modern whois, by the registry that runs their ending (.com, .info, .dev); a few endings still answer only the classic whois (.tr, .io, .de), shown as they wrote it. IP addresses and AS numbers are answered by the regional registry that handed them out. Most registries hide a person’s name and address for privacy.
