<span>Not a valid IPv6 address
A valid IPv6 address consist of 8 groups of 4 hexadecimal numbers separated by colons ":". But that can make for a rather long address of 39 characters. So you're allowed to abbreviate an IPv6 address by getting rid of superfluous zeros. The superfluous zeros are leading zeros in each group of 4 digits, but you have to leave at least one digit in each group. The final elimination of 1 or more groups of all zeros is to use a double colon "::" to replace one or more groups of all zeros. But you can only do that once. Otherwise, it results in an ambiguous IP address. For the example of 2001:1d5::30a::1, there are two such omissions, meaning that the address can be any of
2001:1d5:0:30a:0:0:0:1
2001:1d5:0:0:30a:0:0:1
2001:1d5:0:0:0:30a:0:1
And since you can't determine which it is, it's not a valid IP address.</span>
Answer:
DiffServ
Explanation:
The IP QoS which is fully known as QUALITY OF SERVICE mechanism that involves prioritizing traffic is DIFFERENTIATED SERVICES (DiffServ).
DIFFERENTIATED SERVICES help to differentiate ,arrange ,manage, control and focus on network traffic that are of great significance or important first before network that are less important or by their order of importance in order to provide quality of service and to avoid network traffic congestion which may want to reduce the quality of service when their is to much load on the network .
