- 2. IP Issues DHCP Lap Experience Testing Conflict Management Security Issue Solution References
- 3. Key Issue Number of potential clients 4 Servers 80 PCs 200 Laptops IP Addresses available 200.77.2.2 to 200.77.2.254 IP addresses Number of Clients GREATER THAN IP Addresses available
- 4. DHCP servers Centrally manage IP addresses and provide it to clients automatically. Key Advantage We can configure client network settings at a server instead of configuring them on each client computer. Remember the high turnover rate!
- 5. Step One Adding Server Role
- 6. Step Two Selecting Server Role: DHCP Server
- 7. Step Three Displays a summary of what will be done when setting as a DHCP Server 1. Install DHCP Server 2. Run New Scope Wizard
- 8. Step Four New Scope Wizard Collects the consecutive range of possible addresses that the DHCP server can lease to clients. If we cancel the New Scope Wizard, the DHCP server role will still be installed but the server will not be able to assign the IP addresses
- 9. Step Five Adding a Scope name for identification Adding a description for the scope
- 10. Step Six Assigning a range of consecutive IP addresses that the scope distributes Specifying the subnet mask
- 11. Step Seven Adding addresses or range of address that we do not want the server to distribute One address Range of addresses
- 12. Step Eight Lease duration specifies how long client can use an IP address from this scope The duration should be typically equal to the average time the computer is connected to the network. PC Longer Laptops Shorter Applicable to today’s problem?
- 13. Step Nine New Scope Wizard Completed
- 14. Step Ten
- 15. Authorize DHCP Server Activate Scope
- 16. Client connected to domain with ‘Obtain an IP address automatically’ selected. DHCP Server Stats 249
- 17. Testing exclusions Set a new range of addresses to be excluded
- 18. New IP address 200.77.2.6 Exclusion range (200.77.2.2 to 200.77.2.5) 245
- 19. the amount of time that the DHCP server grants to the DHCP client permission to use a particular IP address. A typical server allows its administrator to set the lease time.
- 20. Connection Status Support Tab Details
- 21. Enable Address Conflict Detection The number you type determines how many times the DHCP server tests an IP address before leasing it to a client. Value between Zero to Six DHCP console tree Select the DHCP Server Action Properties Advanced Tab
- 22. DHCP is an unauthenticated protocol Anyone connected to the network can obtain a lease. Not required to provide credentials! Recommendation Ensure unauthorized persons do not have physical or wireless access to the network
- 23. DHCP Server Servers Manually assigned IP (Static IP as they might need to provide services and access for the clients) PCS Manually assigned IP or longer lease period (Likely to be permanently connected to the physical network) Laptops Dynamic IP address with short lease period (Since Stock Traders might not need to be permanently connected to the network. Hence, releasing whenever the IP is not in use and assigning to new Stock Traders will help in recycling the usage of the limited IP addresses) Not forgetting.. Conflict Management & Security Issues Reservations For static IPs Ensures that a DHCP client is always assigned the same IP address.
