Question

7. Subnet the network of 10.0.0.0/8 into at least 4000 subnets and maximize the number of hosts per subnet. Please fill out the following table #of bits to be borrowed: #of subnets that can be created: #of hosts per subnet: The new prefix length: Subnet the network of 10.0.0.0/8 in such a way that each subnet can support 2000 hosts and maximize the number of subnets. Please fill out the following table: 8. of bits to be borrowed: #of subnets that can be created: of hosts per subnet: The new prefix length: Given the IP address 172.16.34.59 255.255.248.0, please fill out the following table 9.

Answer 1

7)
10.0.0.0/8
for 4000 subnets we need at least 12 bits
now
network bits: 8+12 =20
host bits: 12

# of bits to be borrowed:12
# of subnets that can be created:2^12 = 4096
# of hosts per subnet:2^12 = 4096
The new prefix length:20

8)
10.0.0.0/8
for 2000 subnets we need at least 11 bits
now
subnet bits:13
network bits: 8+13 =21
host bits: 11

# of bits to be borrowed:13
# of subnets that can be created:2^13 = 8192
# of hosts per subnet:2^11 = 2048
The new prefix length:21
