Your server’s IP addresses

Every VICIfast server comes with exactly one public IPv4 address. You see it at the top of your server’s page, in brackets next to the server name — click it once to copy. This is the address your SIP carriers see calls arrive from, the one you point your own domain at, and the one you SSH to. It is dedicated to you: one server, one IP.

Can I add more IP addresses?

Not today. We used to sell extra IPv4 addresses as an add-on, but the add-on is withdrawn: our hosting provider (Hetzner) only allows one primary IPv4 per cloud server, and the alternative — floating IPs — is not supported by the platform yet. We would rather not sell you an IP we can’t deliver.

If a carrier (Twilio Elastic SIP Trunking and Bandwidth are the usual ones) requires a distinct source IP per account, the working route today is a second VICIfast server — every server brings its own dedicated IP. Contact support before ordering and we’ll confirm it fits your setup.

What about IPv6?

Your server also receives an IPv6 /64 from the hosting provider, but the dialer binds to IPv4 and the firewall — including every whitelist rule — is IPv4-only. Use the IPv4 address everywhere. If you or an agent is on an IPv6-only internet connection, whitelist rules won’t match; the agent self-serve portal tells affected users to disable IPv6 and retry.

Looking to whitelist IP addresses instead?

If you came here to let agent home offices, your office VPN, or a partner system through the firewall, that’s a different feature: open your server’s page, click Manage Firewall, and add an Allow rule. Agents can also whitelist their own IP at the self-serve portal (firewall.<your-brand>.com) without opening a ticket. The full walkthrough is in "Manage Firewall — every tab explained".

Good to know

• One server = one IPv4, dedicated to you and included in the plan. A second IP today means a second server.
• Your server’s IP stays with the server for its whole lifetime — carriers can whitelist it permanently. It is only released if you terminate the server.
• The firewall is IPv4-only: IPv6 whitelist entries save but never take effect on the box.
