Engineer Briefing

Most enterprise networks rely on three essential services every day:

• DHCP assigns IP addresses automatically.
• DNS translates names into IP addresses.
• NAT allows private networks to access the Internet.

If any of these services fail, users may lose network access even though routers and switches are working correctly.

Mission Objectives

By the end of this mission, students should understand:

• How DHCP is deployed in enterprises.
• How DNS supports business operations.
• How NAT provides Internet access.
• How these services work together.

1. Enterprise DHCP

Instead of configuring IP addresses manually, businesses use DHCP servers.

Example:

IP Address Assigned

Benefits:

• Automatic configuration.
