Difficulty: MediumIPv4 Addressing and Subnetting

A network administrator is auditing the IPv4 allocation for a newly provisioned department segment assigned the network block 192.168.50.0/26192.168.50.0/26. Which of the following statements accurately describe the addressing characteristics and host capacities for this specific subnet? (Select TWO)

  1. The usable IP address range for host interfaces on this subnet spans from 192.168.50.1192.168.50.1 through 192.168.50.62192.168.50.62.Answer
  2. The subnet accommodates a maximum of 6262 usable host IP addresses.Answer
  3. C
    The subnet accommodates a maximum of 6464 usable host IP addresses.
  4. D
    The IPv4 address 192.168.50.63192.168.50.63 can be assigned as a static IP to a host device's network card.
  5. E
    The IPv4 address 192.168.50.64192.168.50.64 acts as the directed broadcast address for this subnet.

Answer

The two correct statements are that the usable host address range spans from 192.168.50.1192.168.50.1 to 192.168.50.62192.168.50.62, and the subnet accommodates a maximum of 6262 usable host IP addresses.
For a /26 prefix length, there are 32−26=632 - 26 = 6 bits allocated for hosts, giving 26=642^6 = 64 total IP addresses per subnet block. Subtracting the network identifier (192.168.50.0192.168.50.0) and the broadcast address (192.168.50.63192.168.50.63) leaves exactly 6262 usable host addresses spanning from 192.168.50.1192.168.50.1 to 192.168.50.62192.168.50.62.

Step-by-Step Solution

1
Calculate host bits and total IP address count
Host bits h=32−26=6h = 32 - 26 = 6. Total addresses = 26=642^6 = 64.
CIDR /26 leaves 6 bits available for host addressing.
2
Calculate usable host count
Usable hosts = 26−2=64−2=622^6 - 2 = 64 - 2 = 62.
The network identifier address and the directed broadcast address must be reserved.
3
Determine subnet boundaries and usable host IP range
Network ID: 192.168.50.0192.168.50.0. First usable: 192.168.50.1192.168.50.1. Last usable: 192.168.50.62192.168.50.62. Broadcast ID: 192.168.50.63192.168.50.63.
The block size is 64, ranging from .0 to .63.
