Technical Details
Server IP addresses
An IP address is always required for the operation of a vServer or Dedicated Server. This IP address allows Internet users to access the server, for example, to call up a website/domain or to use a game server.
IPv4 addresses
In recent years, the amount of devices connected to the Internet as well as the number of subscribers to the Internet has increased sharply. As a result, the IP range of IPv4 addresses has become increasingly busy, which has ultimately led to a shortage of IPv4 addresses. To counteract this problem, a new IP protocol was introduced in time - IPv6. However, there are still services and devices that do not support IPv6 addresses.
We therefore provide our servers including IPv4 addresses.
- Virtual Server: 1x IPv4 address
- Dedicated Server: 3x IPv4 address
These IP addresses are included at no extra charge. Additional IPv4 addresses can be rented for a small additional charge. The surcharge is unfortunately necessary, as we only have a limited number of IPv4 addresses available and therefore have to actively buy IP addresses on the market, should the IPv4 addresses become scarce.
Own IPv4 Subnet
Optionally, we provide our own IPv4 subnets. The difference between this and the IP addresses we add to our Dedicated Servers and vServers for free is that you get your own V-LAN and are completely segregated from other customers. Therefore, you can freely assign and manage internal IP addresses for cluster communication, for example.
Since IPv4 subnets are also a scarce resource, the IPv4 addresses must be in proportion to the amount of servers. It is therefore not intended to provide a single dedicated server with, for example, an entire /24 IPv4 subnet with 252 usable IP addresses. Therefore we always put a certain minimum server quantity in relation to our offered IPv4 addresses. You can see this ratio in the IPv4 subnet table.
Switch on external subnet
For a small monthly surcharge we offer you the possibility to rent an external IP subnet and run it on our servers. The so-called "announcing" of IP addresses requires the addition of our ASN as a route object. The smallest routable subnet size for IPv4 is a /24 subnet. For IPv6 a /64 subnet. However, we recommend routing a /48 network and then splitting it into smaller /64 subnet segments - we do this for you free of charge.
The connection of IP subnets is charged per route object. For example, if you announce four /24 networks, we would charge you 4x the cost of switching. If you announce 1x /22 and we segment the /22 into 4x /24 networks on the router side, the announcement costs will only be charged once.
Free IPv6 addresses
To promote the use of IPv6 IP addresses, every customer receives IPv6 addresses from us free of charge. The smallest IPv6 unit we actively route is a /64 network. If a larger IPv6 subnet is needed - for example a /48 subnet, we only offer this in the form of next-hop routing. The /48 subnet is delegated to a single IPv6 IP address on the router side. This IPv6 address can be a dedicated router, firewall, or other routing capable device. Using next-hop routing, you can then delegate smaller /64 subnets from a /48 subnet itself.
The background to this approach is router-side caches. A data center router usually only has 16 to 32 GB of RAM. The router must hold the entire routing table of the network and Internet in the main memory. The more IPv6 addresses are actively routed, the more technical load is placed on the data center router, which can lead to problems in the long term due to the immense IP volume with IPv6. We therefore only route /64 networks as the largest segment.
Own V-LAN
If you book your own subnet, you will always get your own V-LAN from us. Since we have no IP-MAC binding within our network, we segment all customers using V-LANs. The advantage of this is that with your own V-LAN you can run all IP addresses on all servers within the V-LAN without additional sharing. The disadvantage is that you can no longer use our free IP addresses.
Therefore you have to decide if you want to get your own subnet or our free IP addresses, but you can use all the advantages of an own V-LAN like - own cumulative traffic view or own IP management.
