Which RFC was created to alleviate the depletion of IPv4 public addresses?
A. RFC 4193
B. RFC 1519
C. RFC 1518
D. RFC 1918
Correct Answer: B
Explanation/Reference:
Explanation:
RFC 4193: Unique Local IPv6 Unicast Addresses.
RFC 1519: Classless Inter-Domain Routing (CIDR): an Address Assignment and Aggregation Strategy .
RFC 1518: An Architecture for IP Address Allocation with CIDR.
RFC 1918: Address Allocation for Private Internets.
The RFC 1518 is Classless Interdomain Routing (CIDR), which is created to save the IPv4 addresses because we can now assign IP addresses classless. Therefore, instead of assigning the whole block of a class B or C address, now smaller blocks of a class can be assigned. For example, instead of assigning a whole block of 200.1.45.0/24, a smaller block, like 200.1.45.0/27 or 200.1.45.32/27, can be assigned.
The RFC 1918 is Address Allocation for Private Internets, which reserves IP addresses for private and internal use. These addresses can be used for networks that do not need to connect to the Internet.
Therefore the RFC 1918 is the best choice to “alleviate the depletion of IPv4 public addresses”.
D is the correct answer
RFC1519 is classless interdomain routing which was creted to make better use of subnetting on public Ipv4 addresses hence improving address allocation and alleviating address exhaustion
Not D ????
