VPS Networking and IP Management

This guide covers the networking information available in VirtFusion, how to find your IP addresses, and how to configure additional IPs if your plan includes them.

Finding Your IP Address

1. Log in to control.teklanhosting.co.uk.
2. Click your VPS.
3. Your primary IPv4 address is shown on the server overview page.
4. For a full list of assigned IPs (including IPv6), go to the Network tab in the server navigation.

IPv4 and IPv6

Every TekLan VPS comes with one IPv4 address. An IPv6 address is also assigned on most plans. To verify IPv6 is working on your server:

ping6 google.com

If IPv6 is not working, check that the interface is configured in your OS network settings. On Ubuntu/Debian with netplan, your /etc/netplan/*.yaml file should include the IPv6 address and gateway provided in VirtFusion.

Reverse DNS (rDNS / PTR Records)

Reverse DNS maps an IP address back to a hostname. This is important for mail servers - without a correct PTR record, outgoing email is likely to be flagged as spam by receiving mail servers.

To set reverse DNS for your VPS IP:

1. Go to the Network tab in VirtFusion.
2. Find the IP address in the IPv4 Addresses table and click the value in the RDNS column to set or update it.
3. Enter the hostname you want the IP to resolve to (for example, mail.yourdomain.com).
4. Save.

Make sure the hostname you set has an A record pointing back to the same IP, otherwise the PTR record will fail validation.

Additional IP Addresses

If your plan includes or supports additional IP addresses, they are managed from the Network tab. Additional IPs need to be configured in your OS as well as allocated in VirtFusion. The exact configuration depends on your distribution:

Ubuntu (netplan):

# Add under your main interface in /etc/netplan/50-cloud-init.yaml
addresses:
  - 203.0.113.1/24
  - 203.0.113.2/24

Run netplan apply to activate the change.

Debian / RHEL-based: Additional IPs are added as alias interfaces. Contact support if you need help with the specific configuration for your OS version.
