IP Check — See the Address Websites See
An IP check shows the public IPv4 and IPv6 addresses your connection presents to the internet, plus location, ISP and ASN. InstantIPCheck runs that check as soon as you open the homepage.
What an IP check actually does
When you visit a site, it sees a public IP. An IP check reads that number from several independent sources so you can confirm IPv4, IPv6, approximate city, ISP and Autonomous System. InstantIPCheck is a free IP checker: no extension, no account.
People search “ip check”, “ipcheck” and “ip checker” for the same job — what is my IP right now, and is it the VPN exit I expected?
How to run an IP check here
Open the InstantIPCheck homepage. The report fills your public addresses automatically. Switch IPv4 and IPv6, copy the number, then scroll to DNS leak and WebRTC leak tests if you are checking a VPN.
To check a different address, use IP lookup and paste any public IPv4, IPv6 or hostname.
IP check versus IP lookup
An IP check is about your current session. IP lookup is about any address — a server in a log, a VPN hostname, or a colleague’s public IP. Both live on InstantIPCheck so you do not bounce between tools.
