Hello world, I'm new to networking and I'm trying to teach myself how this stuff works, but i'm a bit perplexed. I ran across a section in a network design quiz book and I'm having trouble with the subnetting portion. I will post the sample problem and would really appreciate some help if anyone knows how to do it.
Create an IP Address plan using the 192.168.1.0/24 network address to meet the following requirements using Variable Length Subnet Masks (VLSM):
The Core LAN1 (Fa 0/0) will require 100 host IP addresses. Assign Core Fa 0/0 interface the last useable IP address in this subnet.
The Core LAN2 (Fa 0/1) will require 50 host IP addresses. Assign Core Fa 0/1 interface the last useable IP address in this subnet.
VLAN 1, VLAN 10, and VLAN 20 will each require 10 host IP addresses
Assign the first useable IP addresses in VLAN 1 to the S1 management interface.
Assign PC1 the first useable IP address in VLAN 10.
Assign the last useable IP address in VLAN 1, 10, and 20 to R1 LAN1 (Fa 0/0) VLAN sub-interfaces.
Assign R1 S0/0/1 the first useable IP address in 192.168.1.240/30.
Assign Core S0/0/0 the last useable IP address in 192.168.1.240/30.
Assign Core S0/1/0 the first useable IP address in 172.16.0.0/16.
Assign R4 S0/0 the last useable IP address in 172.16.0.0/16.
Assign R4 Loopback 0 the first useable IP address in 172.17.0.0/16.
