6. How accurate is IP address geolocation?

Geolocation accuracy depends on the IP address type and provider. For most IP addresses, accuracy is 95-99% at country level, 80-90% at regional level, and 60-80% at city level. Mobile and dynamic IPs may have lower accuracy.

7. Can I determine a user's exact address by IP?

No, you cannot determine a user's exact physical address by IP address. Geolocation shows approximate location at city or regional level, usually indicating the location of the internet provider or network connection point.

8. How does VPN and proxy detection work?

We use several methods: analyzing IP address ranges of known <a href='https://liberum-vpn.net/' target='_blank' rel='noopener noreferrer' class='vpn-link'>VPN</a> providers, checking against hosting providers, analyzing ASN information, and other technical indicators.

WHOIS Lookup provides complete domain registration information: domain owner, registrar, registration and expiration dates, contact details, domain status, nameservers. Essential for checking domain availability, identifying website owners, and analyzing domain registration history.

19. What is DNS Lookup used for?

DNS Lookup performs detailed analysis of all domain DNS records: A (IPv4 addresses), AAAA (IPv6), MX (mail servers), NS (name servers), TXT (text records for verification), CNAME (aliases), SOA, and others. Helps diagnose email issues, verify DNS configuration, and understand domain infrastructure.

20. What is Security Check?

Security Check is a comprehensive IP address and domain security analysis tool.
