What is dynamic IPv6 address?
Devices on the Internet are assigned a unique IPv6 address, which causes concerns for privacy and tracking. To mitigate the problem, the IPv6 address assigned to a device by the local router is dynamically changed from time to time according to configured parameters.
What are the 3 types of IPv6 addresses?
The three types of IPv6 addresses are: unicast, anycast, and multicast.
- Unicast addresses identify a single interface.
- Anycast addresses identify a set of interfaces in such a way that a packet sent to an anycast address is delivered to a member of the set.
Why is DHCPv6 called stateless DHCPv6?
In this context stateless means that no server keeps track of what addresses have been assigned by which hosts and what addresses are still available for an assignment. A stateful DHCPv6 server provides IPv6 addresses and “other information” to hosts. It also keeps track of the state of each assignment.
What is DHCPv4 and DHCPv6?
DHCPv4 – The DHCP server supplies the subnet mask for each address. A hostname option sets the system-wide host name. DHCPv6 – The subnet mask is supplied by Router Advertisements, not the DHCPv6 server.
How are IPv6 addresses assigned?
IPv6 unicast addresses generally use 64 bits for the network ID and 64 bits for the host ID. The network ID is administratively assigned. The host ID is configured manually or auto-configured by any of the following methods: Using a randomly generated number.
What is the difference between ICMP and ICMPv6?
ICMP messages are not required and are often not allowed within a network for security reasons. ICMP is available for both IPv4 and IPv6. ICMPv4 is the messaging protocol for IPv4. ICMPv6 provides these same services for IPv6 but includes additional functionality.
What are the 3 types of IPv6 addresses Mcq?
Just as with IPv4, a single device’s interface can have more than one address; with IPv6 there are more types of addresses and the same rule applies. There can be link-local, global unicast, and multicast addresses all assigned to the same interface.
Does ip6 change?
In mobile networks, the IPv6 address may change based on the link to which you are connecting, so as you move around you will be generating and using new IPv6 addresses all the time throughout the day.
What is the primary difference between DHCPv4 and DHCPv6 From an operations perspective?
DHCPv4 – The administrator enables DHCP for each interface. Administration is on a per-logical interface basis. DHCPv6 – Explicit configuration is not necessary. This protocol is enabled on a given physical interface.
Should you use DHCPv6?
DHCPv6 servers that assign randomized interface identifiers to end-node devices aid in the protection of the network from attacker reconnaissance attempts. Therefore, organizations should use DHCPv6 servers that are capable of providing randomized interface identifiers to lease requests.
Is DHCPv6 the same as IPv6?
DHCPv6 performs the same role in IPv6 as DHCP does in IPv4. It allows a central server to distribute addresses and other configuration information to a number of hosts.
