What is IPv6?
IPv6 (Internet Protocol version 6) is the latest version of the Internet Protocol, designed to solve IPv4 address exhaustion.
IPv6 Advantages
- Massive Address Space:IPv6 provides 340 undecillion addresses (2^128), virtually inexhaustible
- End-to-End Connectivity:Every device can have a public IP, no NAT translation needed
- Better Performance:Simplified header design, higher routing efficiency
- Enhanced Security:Built-in IPsec support for better encryption and authentication
Connection Types
Supports both IPv4 and IPv6, the ideal configuration for accessing all websites
Only supports IPv4, the most common configuration, can access most websites
Only supports IPv6, less common, some IPv4-only sites may be inaccessible
Network connection error or blocked by firewall
How to Enable IPv6?
- ISP Support:Contact your ISP to confirm if IPv6 service is available
- Router Configuration:Enable IPv6 in router admin interface (DHCPv6 or SLAAC)
- Operating System:Modern OS (Windows 10+, macOS, Linux) support IPv6 by default
- Firewall:Ensure firewall does not block IPv6 traffic
