You Are A Network Administrator In Net Ambit Inc. The Company Has One

You are a Network Administrator in Net Ambit Inc. The company has one external IP, five static servers (including one for DHCP), 12 static printers, and 175 wired personal computers (PCs) or users who receive their IP addresses via DHCP. This is a new setup, and no IP addresses have been assigned yet. You are logged onto a user’s computer locally, and your mapping batch file did not run, so you need to retrieve a file from one of the servers. The internet connection has been set up and is ready for use. You know the number of devices connecting initially, and you are tasked with laying out a plan for IP address allocation and printer assignment. You also need to understand DHCP log events and plan IP assignment for each PC effectively.

Network IP Addressing Strategy for a New Facility at Net Ambit Inc.

Effective IP address planning is fundamental for the smooth operation of a network, especially in a new setup where no addresses have been assigned yet. Given the specified range of 192.167.1.0 to 192.167.1.255, the first step is to determine how to segment this IP range efficiently to accommodate current and future needs. The primary goal is to create an organized, scalable, and manageable IP scheme that separates different device types while ensuring security, ease of management, and sufficient address space.

Designing the IP Address Plan

The IP address space from 192.167.1.0 to 192.167.1.255 represents a Class B network, though with a non-standard private address range. For practical purposes, we will treat this as a subnet with a /24 mask (255.255.255.0). This provides 254 usable IP addresses (192.167.1.1 to 192.167.1.254), suitable for a small-to-medium network segment.

In this scenario, the plan involves segmenting the IPs as follows:

  • Network Gateway: 192.167.1.1
  • DHCP Range: 192.167.1.100 to 192.167.1.200
  • Static IPs for Servers: 192.167.1.2 – 192.167.1.20
  • Static IPs for Printers: 192.167.1.21 – 192.167.1.32
  • Dynamic IPs for PCs: 192.167.1.101 – 192.167.1.99 and 192.167.1.201 – 192.167.1.254

This approach ensures that static devices occupy predictable IPs, while DHCP manages the rest, creating flexibility for expansion. The DHCP scope excludes static IP ranges to prevent conflicts and simplifies network management.

Printer Assignment Strategy

With 12 printers that will be shared among multiple users, an efficient printer assignment plan is vital. Static IPs for printers facilitate easy access, troubleshooting, and maintenance. The printers are assigned static addresses within the range 192.167.1.21 to 192.167.1.32, with each printer receiving a unique address. This static assignment ensures that all users and network devices consistently connect to the correct printer, avoiding address conflicts and simplifying configuration.

To further streamline printer usage, the following strategy can be used:

  1. Create DNS entries for each printer corresponding to their static IP addresses.
  2. Configure each user's device with the printer's network address, either manually or through group policies.
  3. Designate a default printer per user based on department or location to optimize workflow.

Understanding DHCP Log Events

DHCP log files provide detailed records of DHCP server activity, including address allocations, renewals, conflicts, and errors. Recognizing key event IDs helps in troubleshooting and understanding network behavior. Below are five common DHCP event IDs and their significance:

  • ID 10: DHCPREQUEST — A client requests an IP address lease or renewal, indicating a device's attempt to obtain or renew an IP address from the DHCP server.
  • ID 11: DHCPACK — The server acknowledges the client's request, assigning an IP address and providing lease duration and configuration parameters.
  • ID 12: DHCPNAK — The server denies the request, indicating the requested IP is invalid or cannot be assigned, often due to conflicts or misconfigurations.
  • ID 13: DHCPOFFER — The server offers an IP address to a requesting client, which the client can accept or decline.
  • ID 14: DHCPDISCOVER — A client broadcasts a request seeking available DHCP servers when requesting an IP address, usually during initial network connection.

These events help network administrators monitor DHCP activity, diagnose issues like IP conflicts, address exhaustion, or miscommunications, and ensure seamless network operations.

Assigning IPs to 175 PC Devices

Assigning IP addresses to a large number of devices requires meticulous planning and implementation of efficient DHCP policies. Since all 175 PCs are wired, static assignment is impractical; hence, DHCP is the preferred solution. The process involves:

  • Creating a DHCP Scope: Allocate an IP pool (e.g., 192.167.1.101 to 192.167.1.200) to cover all PCs, providing enough addresses for current needs and future growth.
  • Configuring DHCP Options: Set default gateway, DNS server addresses, and other relevant network parameters within DHCP options for consistency across all PCs.
  • Reservation Strategy: For critical machines or devices requiring fixed IPs, create DHCP reservations using MAC addresses to assign specific addresses within the scope.
  • Monitoring and Management: Utilize DHCP logs and management tools to supervise address allocations, detect conflicts, and optimize lease durations.

This systematic approach ensures every PC receives a proper IP address dynamically, minimizing manual configuration errors and simplifying network management. Proper segmentation, clear documentation, and ongoing monitoring are essential to maintain network stability and scalability.

Conclusion

In conclusion, careful planning of IP address allocation and device management is vital as part of establishing a reliable network infrastructure at Net Ambit Inc. Segmenting IP ranges allows for clean management and future expansion. Static IPs for servers and printers reduce network confusion and facilitate troubleshooting, while DHCP simplifies address management for large numbers of PCs. Recognizing DHCP log event types enhances troubleshooting, ensuring network stability. By implementing reservation policies, monitoring logs, and maintaining an organized IP scheme, the network administrator can ensure efficient operation, scalability, and security in the new facility.
