my public IP address tool showing weird errors
0
hey guys, i'm super new to web tools development and just launched a simple 'What is my IP Address' tool, but sometimes it shows really wierd output for the user's public IP adress, or even their external IP.
i'm probably doing something really basic wrong, and here's a fake error log to show what it looks like:
ERROR: Unable to resolve IP address.
Response: {"status":"error","message":"invalid_ip_format"}
Client IP: 0.0.0.0 (Internal Loopback)
Timestamp: 2023-10-27T10:30:00Z
anyone faced this before?

i'm probably doing something really basic wrong, and here's a fake error log to show what it looks like:It looks like you're seeing 'wierd' (typo intended, it's 'weird'!) output because your server is likely capturing an internal IP or proxy address, not the client's actual public IP. For accurate IP lookup and network diagnostics, ensure your server correctly parses `X-Forwarded-For` headers, or consider using client-side JavaScript to query an external IP service like our What is my IP Address tool, or alternatives like IPinfo.io and ip-api.com.

Answered 3 weeks agoOh, wow, that completely clarifies things for me. I was totally missing the proxy aspect and the significance of `X-Forwarded-For` headers. It finally makes sense why I was seeing those weird internal IP addresses.
