What is my IP address?
Want to look like someone else?
Route your traffic through 135M+ real residential IPs in 195+ countries. City, state, ASN. Even mobile carrier targeting. 250 MB free, activated by our team in live chat.
Curious what your IP says about your machine? Try the OS detection check for your operating system, device type and the host OS estimated behind any IP address.
See exactly what every website sees about you
Your IP is the first signal sites use to fingerprint, geo-block or rate-limit you. Here's what's happening behind the scenes.
We read your connection
Your browser opens a request to our lookup endpoint and we extract the source IP from the TCP handshake.
Geo + ASN enrichment
We query public IP intelligence sources to map that IP to a city, ISP, ASN, timezone and currency.
You see what they see
Everything a site can reasonably infer about you from just an IP. Rendered above in plain language.
100% private
We don't log your IP, store the result, or send it anywhere else. Lookup runs and is forgotten.
IPv4 + IPv6
Detects both address families and tells you which one your network is using right now.
ASN + ISP detail
See the autonomous system and ISP your traffic appears to come from. Critical for proxy debugging.
你的 IP 地址暴露了什么
这个 Rainproxy 免费工具会显示每个网站在你连接时看到的公网 IP 地址，以及对应的国家、地区、城市、网络运营商和 ASN，还有浏览器正在发送的请求头。它是确认代理或 VPN 是否真正生效最快的方法。
公网 IP 与内网 IP 的区别
你的设备在局域网内还有一个本地地址，通常类似 192.168.1.20，外部无法看到。公网 IP 才是路由器或运营商向互联网展示的地址，也就是本页显示的那个，你访问的每个网站、接口与广告平台都会记录它。
IP 定位准确吗？
国家几乎总是准确的。城市只是根据注册信息与路由推算出的估计值，往往是最近的大城市而非你所在地。移动网络最不精确，因为运营商会把大片区域汇聚到少数几个出口。
验证代理或 VPN 是否生效
先在不使用代理时打开本页记下 IP，再通过代理或 VPN 打开一次。如果地址、ASN 与国家都发生变化，说明通道生效；如果 IP 变了但请求头里仍带着原始地址，那就是透明代理，不能用于匿名。
如何改变网站看到的 IP
你无法对直接连接的网站隐藏 IP，只能替换它。住宅代理会让请求经由真实家庭网络转发，网站记录到的就是那个地址。Rainproxy 在 150 多个国家提供住宅、移动、ISP 与机房 IP，正是为此而生。
