Zorluk: KolayIPv4 Addressing and Subnetting

A technician is assigning IPv4 addresses to host interfaces within the 10.0.1.0/2910.0.1.0/29 subnet. Which of the following are valid, usable host IP addresses for this subnet? (Select TWO.)

  1. 10.0.1.410.0.1.4Cevap
  2. 10.0.1.610.0.1.6Cevap
  3. C
    10.0.1.010.0.1.0
  4. D
    10.0.1.710.0.1.7

Cevap

The valid usable host IP addresses are 10.0.1.410.0.1.4 and 10.0.1.610.0.1.6.
For the 10.0.1.0/2910.0.1.0/29 network block, a /29/29 mask provides 23=82^3 = 8 total IP addresses. The first address (10.0.1.010.0.1.0) serves as the network ID and the final address (10.0.1.710.0.1.7) serves as the broadcast address. The usable host range includes 10.0.1.110.0.1.1 through 10.0.1.610.0.1.6. Therefore, 10.0.1.410.0.1.4 and 10.0.1.610.0.1.6 are valid usable host addresses.

Adım Adım Çözüm

1
Determine the block size from the prefix length
A /29/29 prefix leaves 3 host bits (32−29=332 - 29 = 3), giving a block size of 23=82^3 = 8 IP addresses.
Calculating the block size identifies the total boundaries of the subnet.
2
Identify the network and broadcast addresses
The network address is 10.0.1.010.0.1.0 and the broadcast address is 10.0.1.710.0.1.7.
The first address in the block is reserved for the network ID and the last address is reserved for broadcast.
3
Determine the usable host IP range
The usable range spans from 10.0.1.110.0.1.1 to 10.0.1.610.0.1.6.
Usable host IPs consist of all addresses strictly between the network ID and the broadcast address.
4
Select options that fall within the usable range
Both 10.0.1.410.0.1.4 and 10.0.1.610.0.1.6 lie within 10.0.1.110.0.1.1 to 10.0.1.610.0.1.6.
Any address inside this range can be assigned to a network interface.
