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).

Add additional network

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
