A network security architect is auditing perimeter firewalls and IP addressing schemes across a enterprise topology. Match each IPv4 address specification to its corresponding RFC 1918 compliance status and public Internet routing behavior.
- Valid RFC 1918 address within the 16-bit block (); filtered by Internet service providers and non-routable across the public Internet.
- Globally routable public IPv4 address residing immediately above the upper boundary of the RFC 1918 16-bit block.
- Valid RFC 1918 address within the 24-bit block () formatted for point-to-point links; non-routable across the public Internet.
- Globally routable public IPv4 address residing immediately above the upper boundary of the RFC 1918 24-bit block.
Cevap
The correct pairings match to the private scope description, to the public space directly above , to the private point-to-point scope description, and to the public space directly above .
Each IP address is accurately mapped according to RFC 1918 boundaries: is private (), is public space immediately above , is private (), and is public space immediately above .
