Exam 200-301 topic 1 question 32 discussion

Global unicast addresses (GUAs), also known as aggregatable global unicast addresses, are globally routable and reachable in the IPv6 Internet. They are equivalent to public IPv4 addresses. They play a significant role in the IPv6 addressing architecture

Ref: IPv6 address - Wikipedia A. multicast A multicast address doesn’t compare to an IPv4 public address. Wrong answer. B. unique local Unique local addresses are addresses analogous to IPv4 private network addresses. Wrong answer. C. link-local A link-local address is also based on the interface identifier, but uses a different format for the network prefix. The prefix field contains the binary value 1111111010. The 54 zeroes that follow make the total network prefix the same for all link-local addresses (fe80::/64 link-local address prefix), rendering them non-routable. Wrong answer. D. global unicast Unicast and anycast addresses are typically composed of two logical parts: a 64-bit network prefix used for routing, and a 64-bit interface identifier used to identify a host's network interface. Correct answer.

The type of IPv6 address that is publicly routable in the same way as IPv4 public addresses is a global unicast address. Global unicast addresses are unique, globally reachable addresses that are assigned to devices that need to communicate with other devices over the Internet. They are similar to IPv4 public addresses in that they can be used to reach devices on other networks, but they are structured differently and use a different address space. Global unicast addresses are identified by the prefix "2000::/3" and are assigned to devices by their network administrator or by an Internet service provider (ISP). They are used for communication between devices on different networks, such as between a device on a LAN and a device on the Internet. It's important to note that global unicast addresses are not the same as link-local addresses, which are used for communication within a single network segment or link and are not intended to be routable over the Internet. Link-local addresses are identified by the prefix "FE80::/10" and are automatically generated by the device when it is connected to a network.

The type of IPv6 address that is publicly routable in the same way as IPv4 public addresses is D. global unicast. Global unicast addresses are similar to public IPv4 addresses in that they are globally unique and can be routed on the public Internet. They are the equivalent of public IPv4 addresses and are assigned to organizations by Regional Internet Registries (RIRs). Global unicast addresses begin with the prefix 2000::/3 and are the most commonly used type of IPv6 address on the Internet. Multicast addresses are used for one-to-many communication and are not routable in the same way as unicast addresses. Unique local addresses (ULA) are used for local communication within an organization and are not meant to be routed on the public Internet. Link-local addresses are used for communication within a local network segment and are not meant to be routed outside of the segment.

public routable in IPv6j is Global Unicast Address

D is a correct answer

what?! yessirr

D is correct

I agree because Global Unicast is similar to Public IPv4 addresses because they are in the same page like 2001::/64 and 209.165.202.0/30

D is correct

Correct answer "D"

D is correct

D is correct

Global unicast: A routable address in the IPv6 Internet, similar to a public IPv4 address.

D is correct.
