Frequently Asked Questions
What is my IP address?
Your IP address is a unique numerical identifier assigned to your device when it connects to the internet. It allows websites and online services to know where to send the data you request. Your public IP is visible to every website you visit, while your private IP is used only within your local network.
Is WhatIP.ca really free?
Yes! During our beta period, all features are completely free. This includes unlimited IP lookups, DNS queries, email deliverability checks, and API access. We plan to introduce paid tiers in the future for heavy commercial use, but core features will always have a free tier.
How accurate is the IP geolocation?
Our geolocation data is highly accurate at the country and city level (typically 95%+ accuracy). However, IP geolocation can never pinpoint an exact physical address — it provides an approximate location based on how IP blocks are allocated and registered. Accuracy varies by region and ISP.
Can I use the API for commercial projects?
During the beta period, you can use our API for commercial projects. Once we exit beta, commercial use will require a paid plan. Please review our Terms of Service for complete details on acceptable use.
How do I remove my IP from a blacklist?
First, use our blacklist checker to identify which blacklists have flagged your IP. Each blacklist has its own removal process — most have a web form for delisting requests. Ensure you've fixed the underlying issue (compromised server, spam, etc.) before requesting removal, or you'll likely be re-listed.
What's the difference between IPv4 and IPv6?
IPv4 addresses are 32-bit numbers (like 192.168.1.1) with about 4.3 billion possible combinations. IPv6 addresses are 128-bit (like 2001:db8::1) with virtually unlimited addresses. IPv6 was created because we've run out of IPv4 addresses. Our tools support both protocols.
