ITPEC FE Morning April 2023 Question 32
ITPEC FE Morning April 2023 — Question 32 of 80
Limited Broadcast Address — 255.255.255.255 sends data to all devices in the local subnet.
- •`255.255.255.255` = limited broadcast — reaches every device on the same subnet
- •Routers do not forward limited broadcast packets beyond the local network segment
- •Common use: DHCP discovery — a client with no IP sends broadcast to find a DHCP server
Why not others:
- (b) Same DNS server — DNS configuration is irrelevant to broadcast delivery
- (c) Default gateway only — the gateway is a single host, not a broadcast target
- (d) Sending to itself — self-referencing uses loopback (127.0.0.1), not broadcast
Key rule: 255.255.255.255 = all hosts on the local subnet; stopped at the router boundary.
