Dynamically Assigning IP Addresses

In Home windows Server 2003, dynamic IP addressing is enabled by Dynamic Host Configuration Protocol (DHCP). The Dynamic Host Configuration Protocol (DHCP) is a protocol and repair that features on the software layer of the TCP/IP protocol suite. The DHCP protocol automates the configuration of TCP/IP shoppers as a result of IP addressing happens by way of the system. You possibly can configure a pc as a DHCP server in order that the DHCP server can mechanically assign IP addresses to DHCP shoppers, and with no guide intervention. IP addresses which are assigned by way of a DHCP server are considered dynamically assigned IP addresses. The DHCP server assigns IP addresses from a predetermined IP handle vary(s).

Utilizing dynamic IP addressing leads the next advantages:

  • Easier administration of IP addressing. You possibly can handle IP addressing from a central location.
  • As a result of the system assigns IP addresses, it results in much less incorrect configurations of IP addresses.

  • You possibly can optionally specify that shoppers acquire different TCP/IP configuration info or parameters mechanically as nicely, reminiscent of:
    • DNS server handle
    • WINS server handle
    • Default gateway
  • A DHCP server have to be put in in your networking surroundings.

To put in the DHCP server, you would wish to carry out the next steps:

  • Set up the DHCP service on the shopper pc
  • Configure the vary of IP addresses which the DHCP server assign IP addresses from. This vary of IP addresses is known as a scope.
  • Activate the scope.
  • In case you are utilizing the Lively Listing listing service, you possibly can authorize the DHCP server within the Lively Listing.

A scopecan be outlined as a set of IP addresses which the DHCP server can allocate or assign to DHCP shoppers. A scope incorporates particular configuration info for shoppers which have IP addresses that are inside the specific scope. Scope info for every DHCP server is restricted to that specific DHCP server solely, and isn’t shared between DHCP servers. Scopes for DHCP servers are configured by directors.

Microsoft Home windows computer systems operating TCP/IP routinely set up the DHCP shopper service as a element of TCP/IP. This consists of servers and workstations operating:

  • Home windows 98, Home windows ME, Home windows NT, Home windows XP, Home windows 2000, and Home windows Server 2003

Troubleshooting TCP/IP Addressing

One of many extra widespread points that come up in TCP/IP networks is the duplication of IP addresses. Duplicated IP addresses end in packets being despatched to the wrong vacation spot computer systems. Home windows working methods can nevertheless detect the duplication of IP addresses.

The method that happens to detect duplicate IP addresses is illustrated under:

  1. When the pc begins, the system checks for any duplicate IP addresses
  2. The TCP/IP protocol stack is disabled on the pc when the system detects duplicate IP addresses.
  3. An error message is proven that signifies the hardware tackle of the opposite system that this pc is in battle with.
  4. The pc that originally owned the duplicate IP handle experiences no interruptions, and operates as usually.
  5. You need to reconfigure the conflicting pc with a singular IP tackle in order that the TCP/IP protocol stack may be enabled on that exact pc once more.

A number of methods for troubleshooting TCP/IP addressing points are briefly mentioned under:

  • If a pc can’t talk with another techniques on the community confirm that the right subnet masks is configured for the pc. Incorrectly configured subnet masks would forestall computer systems on the identical subnet from speaking.
  • If a TCP based mostly pc can’t talk with methods on different LANs, however can talk with techniques on the identical LAN, the issue might be because of an incorrectly configured default gateway. The pc makes use of the default gateway when it wants to speak with computer systems which are situated on different networks. Computer systems that haven’t any specified default gateway can solely talk with computer systems on the identical LAN. It can’t talk with techniques on different LANs.
  • Communication couldn’t be occurring between computer systems as a result of a problem exists that pertains to call decision. In TCP based mostly networks, communication is predicated on IP addresses. If names can’t be resolved to IP addresses, the computer systems wouldn’t have the IP addresses required to speak. In case you are utilizing the Lively Listing listing service, DNS is used for identify decision. DNS identify decision can also be essential to determine a connection to the Web. To make use of DNS for identify decision, the pc should have the IP handle of a DNS server laid out in its TCP/IP properties.
  • If a DHCP server is configured to dynamically assign IP addresses and you’ve got a pc that was assigned the wrong IP handle, it was in all probability because of the pc not with the ability to contact the DHCP server. When this happens, the pc assigns its personal IP handle by way of Automated Personal IP Addressing (APIPA). Computer systems chilly be unable to contact the DHCP server for various causes:
    • An issue may exist with the hardware or software program of the DHCP server.
    • A Knowledge-link protocol challenge might be stopping the pc from speaking with the community.
    • The DHCP server and the shopper are on totally different LANs and there’s no DHCP relay agent. A DHCP relay agent allows a DHCP server to deal with IP handle requests of shoppers which might be situated on a unique LAN.
  • When you have shoppers that can’t acquire IP addresses from the DHCP server, although they will contact the DHCP server, confirm the next:
    • Confirm that the DHCP Server service is operating on the actual server.
    • Verify the precise TCP/IP configuration settings on the DHCP server.
    • In case you are utilizing the Lively Listing listing service, confirm that the DHCP server is permitted by Lively Listing.
    • The DHCP server could possibly be configured with the wrong scope. Verify that the scope is right on the DHCP server, and confirm that it’s lively.
