What's the most reliable way to get a user's public IP address?
0
Hey everyone,
- I was just using the 'What is my IP Address' tool here on AdsVolt, which is super handy!
- I'm wondering, for a SaaS app, what's the most reliable programmatic method to fetch a user's public client IP address?
Thanks in advance!

Ah, the ever-elusive client IP โ a classic chase for anyone doing any serious geo-targeting. For a programmatic approach in your SaaS app, the most reliable method involves inspecting the HTTP headers your server receives:
- Check the
X-Forwarded-FororX-Real-IPheaders first if your application is behind a load balancer or proxy; these indicate the original client IP after network requests. - If not behind a proxy, the
REMOTE_ADDRvariable will provide the direct connection IP. - For quick lookups or external validation, you can use our What is my IP Address tool, or alternatives like ipify.org and Abstract API.
