Network & firewall
IPv4 and IPv6, name servers, additional IP addresses, reverse DNS and the firewall of your cloud server with rules and log.
- IP addresses, name servers and additional IPs of your cloud server Every cloud server receives a fixed IPv4 and an IPv6 address. Here you can read how the addresses are configured, which name servers apply and how to order further IPv4 addresses.
- Setting up an additional IP address in the operating system An additional IPv4 address reaches your server via its own network card and is configured statically in the system. This is how it works on Debian, Ubuntu, AlmaLinux, Rocky Linux, CentOS Stream, openSUSE and FreeBSD.
- Setting reverse DNS (PTR) for your cloud server yourself You set the reverse DNS entry of every IP address of your cloud server yourself in the customer area. A matching A or AAAA record is required.
- Cloud server firewall: rules, quick rules and log Every cloud server has a firewall in front of the system that is active even before the first start. This is how you create rules, order them and read the firewall log.
