What is my IP
This is the public IP address websites see when you visit them, with the network it belongs to, its reverse DNS name and where it is registered.
Your address is read from your connection to our site. We don't keep a record of it.
How to use it
Three steps
- Open the page. Your public address appears straight away.
- Check the network. The network (ASN) usually names your ISP or company.
- Look it up in detail. Use the full IP lookup for the registry record and abuse contact.
Questions
Good to know
Why is this address different from my computer's?
Your computer usually has a private address (such as 192.168.1.20) inside your network. Your router or ISP shares one public address for the whole network.
Why do I see my ISP's name and not mine?
Most home and small business addresses are held by the ISP, so the registry lists the ISP.
Does it change?
Many connections get a new public address from time to time. A static IP from your ISP stays the same.
