What part of an IPv6 address is network and which part host?
IPv6 uses a 128-bit address space. The first 64 bits are the network portion and the remaining 64 bits are the host portion of the address.
How does an IPv6 host acquire its IPv6 configuration?
IPv6 hosts use Neighbor Discovery to obtain a subnet prefix from a local router. Hosts automatically create IPv6 addresses by combining the subnet prefix with an interface ID that is generated from an interface’s MAC address. In the absence of routers, a host can generate only link-local addresses.
How does the DHCPv6 server assign IPv6 addresses?
Our DHCPv6 server will assign IPv6 addresses to all DHCPv6 clients and it will keep track of the bindings. In short, the DHCPv6 servers knows exactly what IPv6 address has been assigned to what host. Stateless works a bit different…the DHCPv6 server does not assign IPv6 addresses to the DHCPv6 clients, this is done through autoconfiguration.
Do you need a Cisco account to use DHCPv6?
An account on Cisco.com is not required. Hierarchical Dynamic Host Configuration Protocol for IPv6 (DHCPv6) for stateless configuration parameters allows a stateless or stateful DHCPv6 client to export configuration parameters (DHCPv6 options) to a local DHCPv6 server pool.
Can a DHCPv6 server default to router X?
In bandwidth constrained networks, a DHCPv6 server may inform clients that a default route is available via router X. This shorter option is discouraged unless there are significant bandwidth limitations.
How to set DHCPv6 server to no Autoconfig?
The ipv6 nd managed-config-flag sets a flag in the router advertisement that tells the hosts that they could use DHCPv6. The last command that ends with no-autoconfig tells the hosts not to use stateless configuration. That’s all we have to do on the DHCPv6 server, let’s move on to the stateless configuration. DHCPv6 Stateless Configuration
