Additional IP networks (blocks)
Additional IP networks can be ordered for a dedicated server in the customer portal (see the "Additional networks" block on a server's Details page).
Public and private IPv4 networks of size up to /26 are available in the portal. Bigger networks can be requested via technical support. Public IPv6 networks are available in chunks of /64.
Additional Network Type | Block sizes available in locations with network redundancy (see Locations) | Block sizes available in locations with reduced network redundancy |
---|---|---|
Public IPv4 | /29 – /26 | /30 – /26 |
Private IPv4 | /29 – /26 | /30 – /26 |
Public IPv6 | /64 | N/A |
Use cases
The primary use case for additional networks is server virtualization, when a single bare metal server hosts multiple virtual machines that require their own IP addresses. An additional network of a bare metal server can also be used in a Level 2 domain as long as the bare metal server is a member of such an L2 domain.
Pricing
Private networks/blocks are free of charge. Public blocks are billed per IP address with prices available in the portal.
Reserved IP addresses
Each IP network has a number of reserved (unusable for a client) IP addresses. The number is 5 for locations with network redundancy (see Locations), and is 3 for locations with reduced network redundancy.
For a location with network redundancy, reserved IPs are (with IPv4 /29 as an example):
Locations with network redundancy | ||
---|---|---|
000 | Network address | |
001 | Switch 1 of a switch group | |
010 | Switch 2 of a switch group | |
011 | Default gateway (Logical switch) | |
.. | Available to a client | |
111 | Broadcast address |
For a location with reduced network redundancy, reserved IPs are (with IPv4 /29 as an example):
Locations with reduced network redundancy | ||
---|---|---|
000 | Network address | |
001 | Default gateway | |
.. | Available to a client | |
111 | Broadcast address |
Number of IPs available to a client per block
Block Size | Number of IPs in a block | Number of IPs available to a client in the locations with network redundancy | Number of IPs available to a client in the locations with reduced network redundancy |
---|---|---|---|
/30 | 4 | N/A | 1 |
/29 | 8 | 3 | 5 |
/28 | 16 | 11 | 13 |
/27 | 32 | 27 | 29 |
/26 | 64 | 59 | 61 |
