IP 知識
我的 IP 地址是什麼？
您的公網 IP 地址、位置和網路詳情 — 即時偵測。
什麼是 IP 地址？
An IP 地址 (Internet Protocol address) is a unique numerical label assigned to every device connected to a computer network. It serves two main functions: 主機或網路介面識別 and 位置定址.
There are two versions in active use today: IPv4 (e.g., 192.168.1.1), which uses 32-bit numbers, and IPv6 (e.g., 2001:db8::1), which uses 128-bit numbers to accommodate the explosion of internet-connected devices.
IP 查詢如何運作？
When you visit this page, your browser makes a request to our API provider, which reads your 公網 IP 地址 from the HTTP connection. The API then cross-references IP allocation databases (maintained by RIRs like ARIN, RIPE, APNIC) to return geolocation and network ownership data — all in real time, no installation required.
動態 IP 與靜態 IP
Most residential connections use a 動態 IP 會定期變更。企業和伺服器通常付費使用 靜態 IP 保持不變 — 適用於託管網站、VPN 和遠端存取。
VPN 與 IP 隱藏
A VPN（虛擬私人網路） 將您的流量透過另一個位置的伺服器路由，用 VPN 伺服器的 IP 替換您的真實 IP。這廣泛用於隱私保護、安全性和繞過地理限制。
IP 地理定位準確度
IP geolocation can identify your 國家 準確率約 99%，您的 城市 to within 50–100 km in most cases. Exact street-level location is not possible from an IP 地址 alone.
常見問題
What is my IP 地址 right now?
Your current 公網 IP 地址 is shown at the top of this page and is detected automatically when you load the page. It is the IP 地址 that the internet sees when you connect from your current network.
Can websites see my IP 地址?
Yes. Every web server you connect to receives your 公網 IP 地址 as part of the HTTP request. This is how the internet routes responses back to you. To hide your IP, you can use a VPN, Tor, or a proxy service.
How do I find someone else's IP 地址?
You can look up any IP 地址 using the "Look up any IP" form above. Simply enter the IP 地址 and click "Look Up" to see its geolocation and network information. Note that 私網 IP 地址es (192.168.x.x, 10.x.x.x) are not publicly routable and will not return useful results.
What does my IP 地址 reveal about me?
Your 公網 IP reveals your approximate 地理位置 (國家, region, 城市), your ISP, and your network's ASN（自治系統編號）. 它不會直接透露您的姓名、住家地址或個人身份。
Why does my location show the wrong 城市?
IP 地理定位基於 ISP 和第三方提供商維護的資料庫。顯示的位置通常是您 ISP 伺服器或網路區塊的註冊位置，可能與您的實際物理位置相差數十或數百公里。
How do I change my IP 地址?
For a 動態 IP, you can often get a new IP by restarting your modem. The most reliable way to change your visible IP is to use a VPN 服務, which replaces your IP with the VPN server's IP. Some ISPs also let you request a 靜態 IP for a fee.
