IP Subnets and Address Ranges

This section provides information about the IP subnets and address ranges applicable to Add and Edit operations.

  • Subnet ID: Subnet ID (or network ID) is a portion of the TCP/IP address that is used to identify a network or a subnet segment. For example, 192.168.0.0 is a Subnet ID for IPv4, and 2001:db8:abcd:0012::0 is a Subnet ID for IPv6.

  • Subnet mask: Identifies host and its network.

  • Prefix length: Prefix length determines the size of the subnet. Prefix length in IPv6 is the equivalent of the subnet mask in IPv4. Supported prefix length is between 0 to 127. 128 is an unsupported prefix length as it leads to subnet with single IP address.

  • Gateway: Network IP device that sends traffic to other networks.

  • Domain: Identifies one or more IP addresses or computers on the Internet. For example, the domain name hpe.com represents about a dozen IP addresses.

    NOTE:

    HPE OneView does not support Single Label Domain (SLD) names.

  • DNS: Supports up to three DNS servers.

    NOTE: Do not use the DNS field when constructing an HPE Synergy Image Streamer deployment network.
  • Name: Unique pre-created name based on <subnet-id> range <next number>. You can edit the name and the limit is 255 characters. Recommended for Image Streamer configurations.

  • IP addresses: A single IP address range with multiple continuous or discontinuous comma-separated fragments. A fragment is a subset of continuous IDs within a pool. Each fragment is mutually exclusive with respect to the other address ranges within the pool. The maximum number of fragments you can add within a range is 100 fragments.

    NOTE:
    • By default, IPv4 address ranges are enabled.
    • You cannot remove a range or subnet that is associated with other resources or has addresses in use.
