关于ifconfig.me网站仅显示IPv6地址不展示IPv4地址的技术问询

Hey there! I totally get where you're coming from—ifconfig.me is such a handy tool for quick network info checks, so it’s definitely a letdown that it’s not showing your IPv4 details. Let’s break down some likely reasons why this might be happening:

• Your network prioritizes or uses only IPv6: If your ISP or local network is set up to route traffic exclusively over IPv6, the ifconfig.me server will only receive your IPv6 address when you connect. In that case, there’s no IPv4 address for the site to report back.
• Server-side infrastructure choices: The site might be running on an IPv6-only server stack, meaning it doesn’t handle IPv4 connections at all. Even if your device has an IPv4 address, the server can’t detect it because it’s not configured to listen for IPv4 traffic.
• Connection routing quirks: Sometimes even with an active IPv4 address, your traffic to ifconfig.me could be routed through an IPv6 tunnel or proxy. This makes the server only see your IPv6 endpoint, not your actual IPv4 address.

I couldn’t agree more with you—adding IPv4 information would turn this already useful tool into a perfect one-stop for quick network diagnostics. It’s such a straightforward, no-fuss utility that filling that gap would make it even more indispensable for quick checks.
