      Frequently Asked Questions
      
    
      
      What are A and AAAA records?
      
      A records map a domain name to an IPv4 address (e.g. 142.251.116.100). AAAA records map to IPv6 addresses (e.g. 2607:f8b0:4023::64). Most domains have both.
      
    
      
    
      
      Is this tool free?
      
      Yes, completely free with no signup. For programmatic access, use our DNS API: GET /v1/agent-dns/api/resolve/{domain}. See the API guide.
      
    
      
    
      
      How is this different from dig or nslookup?
      
      This tool performs the same DNS resolution as dig or nslookup, but runs in your browser with no terminal needed. It also provides a JSON API you can integrate into your own applications.
      
    
      
    
      
      Why does my domain show no records?
      
      If a domain shows no A or AAAA records, it might not have DNS configured, could be using only CNAME records (which resolve to another domain), or the domain might not exist.
      
    
      
    
      
      Can I use the API programmatically?
      
      Yes. Make a GET request to https://agent-gateway-kappa.vercel.app/v1/agent-dns/api/resolve/{domain} and you'll receive a JSON response with IPv4 and IPv6 records, query time, and timestamp.
