DHCP and DNS Server configuration using Cisco Packet Tracer

Objective

The primary objective of this project was to configure a DHCP server in Cisco Packet Tracer, allowing network clients to automatically receive IP addresses and necessary network configurations.

Devices used

• 1 DHCP Server
• 1 DNS Server
• 4 Switches
• 1 Router
• 15 PCs

Arranging Network Topology

Setting IP Addresses

DHCP Server (192.168.0.69)

Enabling DHCP Service & creating pools

• serverPool - from 192.168.1.0
• Pool-1 - from 192.168.2.0
• Pool-2 - from 192.168.3.0

DNS Server (192.168.0.2)

Configuring Router & DHCP Relay

Router Configuration

IP Addresses for each Interface

• G0/0 : 192.168.0.1 (Facing Server side)
• G1/0 : 192.168.1.1
• G2/0 : 192.168.2.1
• G3/0 : 192.168.3.1

DNS Server Address: 192.168.0.2

DHCP Relay setup for each Interface

Router# conf t
Router(config)# int g0/0
Router(config-if)# ip helper-address 192.168.0.69
Router(config-if)# exit
Router(config)# int g1/0
Router(config-if)# ip helper-address 192.168.0.69
Router(config-if)# exit
Router(config)# int g2/0
Router(config-if)# ip helper-address 192.168.0.69
Router(config-if)# exit
Router(config)# int g3/0
Router(config-if)# ip helper-address 192.168.0.69
Router(config-if)# exit
Router(config)# exit

Setting IP addresses to DHCP for each client

Overall Topology

Conclusion

With the setup of a DHCP and DNS server, IP address management and domain name resolution can be automated, streamlining network operations for dynamic and scalable environments.
