How is RFC 1918 addressing used in a network? (CCNA 200-301)
How is RFC 1918 addressing used in a network?
A. They are used to access the Internet from the internal network without conversion.
B. They are used in place of public addresses for Increased security.
C. They are used with NAT to preserve public IPv4 addresses.
D. They are used by Internet Service Providers to route over the Internet.
Solution
Correct answer: C. They are used with NAT to preserve public IPv4 addresses.
RFC 1918 addresses are private IP addresses that are not routable on the Internet. They are used within a private network, such as a home or corporate network, to conserve public IPv4 addresses. Network Address Translation (NAT) is used to translate these private addresses to public addresses when accessing the Internet. This allows multiple devices on a private network to share a single public IP address, conserving public IPv4 addresses.
