Hello @usernameusernameusername456,

Subnetting:

--LAN1 - 29 users.

To accommodate 29 users, we need a subnet with at least 32 usable host addresses. We'll use the /27 subnet mask (255.255.255.224) for LAN1.

LAN1 Subnet: 192.168.0.0/27 First usable IP: 192.168.0.1 Last usable IP: 192.168.0.30

--LAN2 - 61 users.

To accommodate 61 users, we need a subnet with at least 64 usable host addresses. We'll use the /26 subnet mask (255.255.255.192) for LAN2.

LAN2 Subnet: 192.168.0.64/26 First usable IP: 192.168.0.65 Last usable IP: 192.168.0.126

--LAN3 - 14 users.

To accommodate 14 users, we need a subnet with at least 16 usable host addresses. We'll use the /28 subnet mask (255.255.255.240) for LAN3.

LAN3 Subnet: 192.168.0.128/28 First usable IP: 192.168.0.129 Last usable IP: 192.168.0.142

--LAN4 - 5 users.

To accommodate 5 users, we need a subnet with at least 8 usable host addresses. We'll use the /29 subnet mask (255.255.255.248) for LAN4.

LAN4 Subnet: 192.168.0.144/29 First usable IP: 192.168.0.145 Last usable IP: 192.168.0.150

Point to Point connections:

R1 - R2 Subnet: 10.10.10.0/30 First usable IP: 10.10.10.1 Last usable IP: 10.10.10.2

R2 - R3 Subnet: 10.10.10.4/30 First usable IP: 10.10.10.5 Last usable IP: 10.10.10.6

IP assign.:

LAN1:

-Computer: 192.168.0.1

-Router Interface: 192.168.0.30 *

LAN2:

-Computer: 192.168.0.65

-Router Interface: 192.168.0.126 *

LAN3:

-Computer: 192.168.0.129

-Router Interface: 192.168.0.142 *

LAN4:

-Computer: 192.168.0.145

-Router Interface: 192.168.0.150 *

* On routers add the ip helper adress to act as a relay dhcp and send the dhcp messages to the DHCP server. Follow/read this: https://community.cisco.com/t5/networking-knowledge-base/configuring-ip-helper-address-to-issue-ip-address-from-dhcp/ta-p/4680974

Hello @usernameusernameusername456,

Configure the IP address of the DNS server. Double-click on the DNS server device to open the configuration window. Go to the "Config" tab, select the appropriate interface, and assign an IP address that is within the same network as your web server. 

Set the DNS records on the DNS server. Look for DNS server software or services running on the server and access its configuration:

--Create a new zone for the "Lab100" domain. In the DNS server configuration, create a new zone for the "Lab100" domain. Specify the domain name as "lab100" and configure the zone file or records associated with it.

--Add the necessary DNS records. Within the "Lab100" zone, add the required DNS records for your web server. Specifically, you will need an "A" record that maps the hostname (e.g., "www") to the IP address of your web server.

Now, the DNS server is configured with the appropriate DNS records for the "Lab100" domain. When clients query this DNS server for the IP address of "www.lab100.com" or "lab100.com", it will respond with the IP address of your web server.

@usernameusernameusername456,

PC1 has no Gateway and no DNS configured......

Review all you IP plan - check DNS server also -
