Networking & firewall

Public IPs, reserved IPs, and the ports we let in.

Public IPv4

Every instance ships with a public IPv4. The address is stable across start/stop cycles; it only changes on rebuild or delete.

Reserved IPs

On STANDARD and up you can pin an address so a rebuild keeps it. Reserved IPs cost ₦500/mo and the address stays yours while the account is active.

Firewall defaults

New instances start with SSH (22) open to the world and everything else closed. You can open specific ports from the Networking tab; rules apply within a minute.

  • Port 25 (SMTP) is blocked on every plan — SendGrid, Postmark, or SES are the right way to send mail at scale.
  • ICMP is allowed so ping and traceroute work.
  • IPv6 is on the roadmap; NAT'd egress keeps things simple until then.

DNS

Point an A record at your instance IP at your registrar. We don't run nameservers — keep DNS wherever you already have it.
