Why You Should Manage and Protect Your DHCP Server

Why You Should Manage and Protect Your DHCP Server – Because internet protocol (IP) addresses are considered essential in networking, it is impossible to connect to any network without one. It is also necessary to have a solid understanding of how a network administrator configures their dynamic host control protocol (DHCP) server significantly impacts the efficiency with which the network operates. When it comes to achieving the best results possible in terms of network connectivity, some individuals focus an excessive amount of attention on the cabling layout of the network. Despite this, it is essential to point out that the infrastructure must work with the DHCP server to achieve the best possible results.

What are the most important aspects to keep an eye out for when managing DHCP servers?

All devices connected to the network receive their addresses from the DHCP server, which is their point of responsibility. Because of this, if something goes wrong while configuring this server, it could very well cause the entire network to become inoperable. The following is a list of essential considerations to keep in mind:

  • The beginning and ending IP address pool used by the DHCP server.
  • Take care of reservations for IP addresses.
  • Maintain a high level of surveillance over your static IP addresses.

It is essential to determine the first address your server can lease because doing so will allow you to choose the number of devices that can go into your network segment at any given time. Once this number has been determined, you can move on to the next step. You can consciously choose your subnet mask based on the number of devices.

Static IP addresses are always recommended for use on devices hosting shared resources. This must be the case because it makes the network administrator’s job much more straightforward when connecting other users to the relevant resource. If you have a shared resource whose address constantly changes, the network or systems administrator will have difficulty reconnecting users whenever the DHCP server leases new addresses. This is because the administrator will have to run around.

Advice on the Administration of Static IP Addresses

A system administrator must first ensure that static IP addresses are not leased to any other devices on the network besides the one used. This indicates that the network administrator must ensure that such lessons are reserved, in addition to ensuring that they are either above or below the lease range provided by the DHCP server.

You may also be able to bind specific IP addresses to the media access control (MAC) identity of the device you are using, but this will depend on the type of router or DHCP server that you are utilizing. Because MAC identities are never shared between devices, doing so will give you the peace of mind that no other appliance will ever be able to use the address mentioned above.

As an administrator, you might also be required to run routine network scans on the system to identify the various devices connected to it. This practice helps in weeding out devices that might have incorrect addresses, which can create conflicts and restrict your network performance. Portable computers are the most likely culprits behind incorrect addresses because their owners move from one office to another, causing the computers to connect to a new network each time. When you run a scan of your network and find devices with incorrect configurations, you need to take action by correcting those devices and also advising the owners or users of those devices on the significance of ensuring their devices are correctly configured for improved connectivity.
