Multiple IPv4 per server
Add or release IPs from the dashboard. Each comes from a clean range — no shared subnet history, no spam-list inheritance.
Per-trunk IP pinning
When a carrier requires a distinct source IP per account, pin the outbound trunk to one of your dedicated IPs. PJSIP transport binds to that IP for outgoing traffic.
Firewall whitelist by IP
Whitelist your agent home offices, your office VPN, or partner systems. Combined with the agent self-serve portal, you do not have to babysit IP changes.
IPv6 ready
Every server gets an IPv6 /64 by default. Tools that need it (some carriers, some monitoring) have it; tools that do not are unaffected.
Reverse DNS you control
Set the PTR record on each IP from the dashboard. Useful for outbound deliverability when your carrier checks that rDNS matches a recognizable domain.
Cost surfaced up front
Each additional IPv4 has a Hetzner monthly fee — roughly $1/mo. Pass-through at cost, no markup. The order screen shows the exact monthly bump before you confirm.
Release without re-provision
Outgrew an IP? Release from the dashboard. The IP unbinds from the server within seconds; firewall rules referencing it are flagged for cleanup. No SSH-and-edit-/etc/network/interfaces dance.
Audit-logged changes
IP add / release / rDNS change all land in the server AuditLog with actor + timestamp + IP. Useful for compliance teams that audit network changes monthly.
