What is this page for?
Your public IP address is the identifier your connection presents to every server you visit. It is useful to know when a provider asks you to allow your company on their service, when you set up remote access or a VPN, or simply to check which internet exit you are going through.
The blacklist check, for its part, mainly concerns your emails. If the address your company sends mail from appears on an anti-spam list, your messages may be blocked or filed as junk by your clients, often without you being told. A listed IP can be fixed, but you first have to know about it. If a doubt comes up here, write to us: we'll look into it with you.
