Which of the following IPv4 networks are reserved by IANA for private address assignment and private routing? (Choose three.)
Which of the following IPv4 networks are reserved by IANA for private address assignment and private routing? (Choose three.)
The IPv4 address spaces reserved by the Internet Assigned Numbers Authority (IANA) for private address assignments and private routing include 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. These address ranges cannot be used on the public internet and are intended specifically for use within private networks.
The Internet Engineering Task Force (IETF) has directed the Internet Assigned Numbers Authority (IANA) to reserve the following IPv4 address ranges for private networks: 24-bit block 10.0.0.0 – 10.255.255.255 Host ID size 24 bits Mask bits 8 20-bit block 172.16.0.0 – 172.31.255.255 Host ID size 20 bits Mask bits 12 16-bit block 192.168.0.0 – 192.168.255.255 Host ID size 16 bits Mask bits 16
Private Address Ranges Class A: 10.0. 0.0 to 10.255. 255.255. Class B: 172.16. 0.0 to 172.31. 255.255. Class C: 192.168. 0.0 to 192.168. 255.255.
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets: 10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix) https://datatracker.ietf.org/doc/html/rfc1918#section-3
