Subnet masks (IPv4) and prefixes (IPv6) - IBM
2010年10月10日 · The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as an integer between 1 through 128. For example: 2001:db8:abcd:0012::0/64 specifies a subnet with a range of IP addresses from: 2001:db8:abcd:0012: 0000:0000:0000:0000 - 2001:db8:abcd ...
IPv6 prefixes - IBM
The IPv6 prefix concept is similar to IPv4 subnetting. An IPv6 address with a prefix is written as an IPv6 address followed by a decimal number representing the number of bits in the address that constitute the prefix.

(Optional) Specify the subnet and network prefix notation on which the target node is located. Description. This command adds a node discovery subnet where candidate nodes can be discovered. There are a total of 16 slots (16 records) in the subnets table.
ibv_query_gid
Description. The ibv_query_gid() function returns the MAC address of the NIC in the subnet_prefix parameter and 0 in the interface_id identifier.

For example, 192.168.100.14/24 represents the IPv4 address, 192.168.100.14, and its associated routing prefix 192.168.100.0, or equivalently, its subnet mask 255.255.255.0 (which has 24 leading 1 bits). To create a new subnet, complete the following steps: You cannot assign the subnet that has already been assigned to another virtual machine.
Textual representation of IPv6 prefixes - IBM
When writing both a node address and a prefix of that node address (for example, the node's subnet prefix), the two can be combined as in the following examples: Node address - 2001:DB8:0:CD30:123:4567:89AB:CDEF

If the node is part of a system, then the system gateway, subnet, and prefix are used unless specified otherwise. If the node is a candidate node, the subnet, prefix, and gateway must be specified. If you specify an IPV4 or IPV6 address, but do not provide a gateway, mask, or prefix, then the existing gateway, mask, and prefix values are preserved.
Planning for global identifier prefixes - IBM
Each subnet in the InfiniBand network must be assigned a GID prefix, which is used to identify the subnet for addressing purposes. The GID prefix is an arbitrary assignment with a format of xx:xx:xx:xx:xx:xx:xx:xx (for example, FE:80:00:00:00:00:00:01). The default GID prefix is FE:80:00:00:00:00:00:00. The GID prefix is set by the subnet manager.

-prefix subnet_prefix (Required) Specifies the prefix of subnet. The value for IPv4 addresses can range from 1 to 31. The value for IPv6 addresses can range from 1 to 127.-gw gateway (Optional) Specifies the IPv4 or IPv6 gateway address. The value consists in standard format for IPv4 address, or IPv6 address of a string of 40 characters.-vlan ...

The prefix length for an IPv4 block is between 0 and 32. networking.clusterNetwork.hostPrefix: The subnet prefix length to assign to each individual node. For example, if hostPrefix is set to 23 then each node is assigned a /23 subnet out of the given cidr. A hostPrefix value of 23 provides 510 (2^(32 - 23) - 2) pod IP addresses. A subnet prefix.
