Explanation

MAC (Media Access Control) filtering allows a network administrator to create a whitelist of approved device MAC addresses. Only devices whose MAC addresses are on the approved list can connect to the network, effectively blocking any unknown or unauthorized hardware. Static IPs (A) control addressing but do not block unauthorized devices from connecting at the hardware level. Disabling DNS (B) would break name resolution for everyone, disrupting legitimate use. Disabling a local proxy server (C) affects web traffic routing and does nothing to restrict network access at the connection level.
