What two statements about IPv6 addresses are true? This task contains the radio buttons and checkboxes for options. The shortcut

Oliga [24]

Answer:

A and C

Explanation:

Option A:

In IPv6 there is a rule to reduce an IPv6 address when there are two or more consecutive segments of zeros just one time. This rule says that you can change the consecutive zeros for “::”

Here is an example

How to reduce the following IPv6 address?

ff02:0000:0000:0000:0000:0000:0000:d500

Ans: ff02::d500

Example 2:

2001:ed02:0000:0000:cf14:0000:0000:de95

Incorrect Answer -> 2001:ed02::cf14::de95

Since the rule says that you can apply “::” just one time, you need to do it for a per of zero segments, so the correct answer is:

Correct Answer -> 2001:ed02::cf14:0:0:de95

Or

2001:ed02:0:0:cf14::de95

Option C:

Since in IPv6 there are $2^{128}$ available addresses which means 340.282.366.920.938.463.463.374.607.431.768.211.456 (too many addresses), there is no need of NAT solution, so each device can have its own IP address by the same interface to have access through the internet if needed. If not, you can block the access through internet by the firewall.

In terms of computer networking. what is PING?

Andrew [12]

Ping means how much of a delay there is in your connection. The lower the ping, the smaller the delay. This plays an important role in online gaming. If your ping is 350, then your delay is 350ths of a second.
