    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
