Zorluk: KolayIPv4 Addressing and Subnetting

A network technician is setting up a new network segment using the IP block 10.0.4.0/2410.0.4.0/24. Following standard configuration guidelines, the default gateway will be assigned the last usable host IP address in the subnet. What is the last usable IPv4 host address in the 10.0.4.0/2410.0.4.0/24 network?

Cevap: 10.0.4.254

Cevap

The last usable IPv4 host address in the 10.0.4.0/2410.0.4.0/24 network is 10.0.4.25410.0.4.254.
For a /24/24 IPv4 subnet, the address space covers 256 total IP addresses (10.0.4.010.0.4.0 to 10.0.4.25510.0.4.255). The first address (10.0.4.010.0.4.0) serves as the network ID and the last address (10.0.4.25510.0.4.255) serves as the broadcast address. Thus, the assignable host range is 10.0.4.110.0.4.1 through 10.0.4.25410.0.4.254, making 10.0.4.25410.0.4.254 the last usable host address.

Adım Adım Çözüm

1
Identify the network address and broadcast address for 10.0.4.0/2410.0.4.0/24.
Network address is 10.0.4.010.0.4.0 and broadcast address is 10.0.4.25510.0.4.255.
A /24/24 prefix provides 256 total IP addresses in the final octet (range 0–255).
2
Determine the range of usable host IP addresses.
The usable host address range spans from 10.0.4.110.0.4.1 to 10.0.4.25410.0.4.254.
The network address (10.0.4.010.0.4.0) and the broadcast address (10.0.4.25510.0.4.255) cannot be assigned to hosts.
3
Select the last assignable host address.
10.0.4.25410.0.4.254
It is the highest usable IP address immediately preceding the broadcast address.
