IPv6: Definition, Use Cases, and Examples

By · Updated
TL;DR:

IPv6 is the 6th version of the Internet Protocol. Address is 128 bits (2001:db8::1) instead of 32 bits in IPv4. Solves address exhaustion. In DNS it uses the AAAA record. Supported by all modern ISPs and cloud providers. Around 45% of global traffic in 2026.

Why check IP Geolocation?

IP geolocation identifies the location of a server, user, or traffic source. Essential for CDN configuration, GeoIP rules, and security anomaly analysis.

Accurate Geolocation

Country, region, city, postal code, and timezone by IP.

ASN / ISP Data

Provider, autonomous system name, and network range.

Proxy Detector

VPN, proxy, Tor, and hosting flags — protection against fraud and bots.

Common Mistakes

❌
Assuming geolocation is exactGeoIP gives city-level accuracy, not street-level. Use additional signals for critical decisions.
❌
Ignoring VPN flagsVPN/proxy changes the real geolocation. Always check for VPN/proxy flags.
❌
Blocking entire countriesGeoIP blocking is easily bypassed with VPN. Use it as one signal, not the only one.
❌
Confusing IP and DNS geolocationCDN can have IPs in one region and DNS servers in another. Check both.

Best Practices

✓
Use for CDN configurationCheck which CDN PoP serves users in different regions.
✓
Check suspicious request IPsOn anomalous traffic — first check the ASN and source country.
✓
Compare before and after CDNEnsure the CDN hides the real server IP rather than exposing it.
✓
Monitor IP changesSudden IP geolocation change can signal DNS hijacking or BGP route hijack.
