Hello everyone, and welcome again
In this video, we will talk about assigning Static or Permanent IP Addresses to your Network
Computers and Devices. This is much of a theoretical lesson than practical, so you need to listen with patience
When organizing your home or office network, it is much easier to manually assign each
computer a static IP address of its own, instead of using DHCP settings
DHCP stands for, Dynamic Host Configuration Protocol, which automatically assign IP addresses
to connected network computers. By default, in Windows, network adapters are set to obtain IP address automatically
so if there are DHCP settings configured, then your network computers will automatically
obtain an IP address. But the problem with receiving an automatic IP address from DHCP configuration depends
on, first come first serve basis. That means, each computer request and be assigned an address, every time it's booted up
So, which one will be booted first, will get an IP address first
Even though computer will assigned addresses automatically, but they will not be static
For instance, a computer having an IP address of 192.168.1.110, may be assigned a different
address on next boot up. If you have several computers and devices in your home or office network, then assigning
them a static or, permanent IP address is a good idea. While troubleshooting network problems, it's annoying to move to each machine to know what
IP address they have. Having static IP address in networks also prevents conflicts between devices, and you
can manage network computers more easily. You can easily assign a static IP to a network computer by changing the LAN adapter settings
for Network and Sharing Center. Then manually enter the IP address from TCP, IP Protocol
But this might cause a conflict, if the same IP address is given to another computer or
devices in same network, and for an organization having hundreds of computer in network environment
it is not a good idea to manually enter the IP addresses
In this tutorial will configure the router to automatically assign a fixed IP to a particular
computer or device, having a certain MAC address. MAC, Media Access Control Addresses, also called the Physical Addresses, are unique
identifier codes assigned to network interface cards or devices, for communications on the network
MAC addresses are most often assigned by the manufacturer, and are stored in the device hardware
Assigning IP addresses based on devices MAC addresses, will make the IP address permanent
unless you change them yourself. When you send or receive data over network, then computers are identified by their IP
addresses, and which IP address correspond to which computer is identified by the MAC address
To change or configure the router settings, first you need to know, how you can access them
You can find the instructions in the documentation that comes with the router
Mostly, the login link, user name and password are also printed to the back side of the router
Do remember, this tutorial is just for information purpose, as different routers are configured differently
This tutorial will give you a little bit idea about how to set the things up
For instance, I can access my TP link router settings by opening, 192.168.1.1 in any web
or browser, and the default user name and password are, admin. Before I start assigning static IP addresses to my network computers and devices, let's
first see, how my router is already distributing the IP addresses. So, I click the DHCP link from the left side pane, and under DHCP settings, you can see
that DHCP server is enabled. Here you can also specify the numbers of total IP addresses that you want to distribute by
assigning starting and ending IP addresses. As I have assign 100 to 130, that means, 31st device will not be able to connect to my network
as the maximum limit of distributing IP addresses is set to 30
The address lease time is set to 120 minutes by default, which means, if my network devices
does not have static IP addresses, then a network user will be allowed to keep connecting
to the router for the specified minutes with the current DHCP address
The default gateway is the same address that I use to access my router settings, and the
other computers and devices in my network will have the same gateway address, as they
are connected through this gateway. I can see a list of the connected computers and devices in my network by clicking on DHCP
clients list. Here you can see the client name, the MAC or physical address of the device, and IP
address assigned to them. If the IP addresses are not permanent then you will see the time duration under lease
time, else for permanent IPs. Lease time does not matter. As you can see the list of devices currently connected with my network, where I have already
assigned proper names for network computers, but the IP addresses are not in order
For instance, I want 192.168.1.101 for Network Computer KCI PC1, then 192.168.1.102 for Network
Computer KCI PC2, and so on, so it will become very easy for me to remember the IP addresses
as they will be according to computer names, like 101 for PC1, 102 for PC2, and so on
What I need to do now is to, set the address reservation for particular MAC addresses
which I can do by clicking on Addresses Reservation link. To allot a permanent IP address to a particular MAC address, I click on Add New button
Here I only need to fill 3 fields, the MAC address of the device, the IP address that
I want to reserve for that particular device, or either I want to enable that specific entry
for now, or not. So, first I copy the MAC address of the device from the DHCP client list
Do remember that, DHCP client list will only show those devices which are already connected
to my network. If you are setting up a new network for the first time, then you need to move to that
particular computer, and have to write down the physical address or MAC address, which
you can check either by, opening the properties of Local Area Network, or, you can run IP
config slash all command at command prompt
Once you note down the MAC address of a particular computer, type the address, in MAC address
field and then, assign a reserved IP address for that particular computer, which should
be in the range of start IP and end IP addresses. Remember now, let the status enabled and then click Save button
By repeating the same steps, I will assign permanent IP addresses to each and every computer
and device in my network
Once I finished adding all the devices, I need to reboot the router for the configuration
to take effect, which you can either do from System Tools link, or you can turn off and
turn on the router again
After restarting the router, you can check the configuration in DHCP client list to see
if all the devices have the permanent addresses as you wanted
As I said earlier, there are a lot of benefits of assigning permanent IP addresses to network
devices, and one of them is controlling network bandwidth. Our next tutorial will be about, controlling Internet Bandwidth and Speed over Network
which is only possible if my network devices have fixed IP addresses
