On the router’s web admin interface, look for an advanced settings category called LAN. In it, go to the LAN IP settings section or tab, and change the value of the Subnet Mask with the one you want. Click or tap on Apply, Save, or OK.

How do I change my subnet mask?
Steps
- To specify a subnet mask for an interface, enter the following command: ifconfig interface_name netmask mask.
- To change the subnet mask for an interface that has been configured with a primary and an alias address, enter the following command for each IP address: ifconfig interface_name IP address netmask mask.
How do I find my subnet mask on Windows 10?
- In the Windows search fields, type cmd, to open command prompt.
- Press Enter.
- Type ipconfig/all press Enter.
- Find your network settings.
- Your PC’s IP address and your network Subnet Mask and Gateway will be listed.
How do I change the subnet mask on my laptop?
Right-click on the network adapter you want to assign an IP address and click Properties. Highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button. Now change the IP, Subnet mask, Default Gateway, and DNS Server Addresses. When you’re finished click OK.
Should I change subnet mask?
Why do we change a Subnet Mask? It is a recommended procedure for increasing a DHCP scope when the current scope has entirely consumed the current subnet mask. However, this method requires you to change all subnet hosts and gateways.
Is subnet mask always the same?
Subnet masks always work from left to right. Devices are said to be within the same subnet if their IP Address starts with the same digits, but ends with a different set of digits.If the subnet mask is 255.255. 255.0, then the first three octets of all devices must be the same.
How do you solve subnet mask problems?
Solution-
- Subnet mask = 255.255.255.0.
- Number of bits borrowed from Host ID part = m.
- So, number of subnets possible = 2m
- Number of bits available for Hosts = HID – m.
- So, number of hosts that can be configured = 2(HID – m) – 2.
What happens when you change the subnet mask?
If you change the subnet mask on the statically-configured devices at the same time as you change the subnet mask on DHCP server(s) then you’ll see no changes in behaviour. If you leave devices with the old subnet mask they’ll only be able to talk to devices that still have addresses in the old subnet’s range.
Where do I find my subnet mask?
On Android
- Go to Settings > Wireless & Networks > Wi-Fi.
- Tap on the network you’re connected to.
- You will find the subnet mask along with other network details.
What is NIC IP address?
Network Interface Card is in-short called NIC. NIC is also referred to as an Ethernet card and network adapter. It is an expansion card or hardware interface that enables a computer to connect to a network; such as a home network, or the Internet using an Ethernet cable with an RJ-45 connector.
How do I get to a different subnet?
How to Connect Computers That Are on 2 Different Subnets
- Connect the computers to the network.
- Connect the routers to each other.
- Enable a routing protocol in each subnet’s router.
- Allow time for the routing tables to update.
How do I change my IP address using CMD?
For Windows users
- Get to a command prompt. (START, run, cmd).
- Type “ipconfig /release” (without the quotes, on the command line by itself).
- Shut down computer.
- Turn off computer.
- Turn off all ethernet hubs/switches.
- Turn off cable/DSL modem.
- Leave off overnight.
- Turn everything back on.
Why is subnet mask always 255?
A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s.The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address. Neither can be assigned to hosts, as they are reserved for these special purposes.
Why is subnet mask needed?
– A subnet mask allows identification of host part and network part of an IP address.- Subnet mask is utilized for isolating the network id and host ids. – This is to reduce the broadcast domain or to reduce heavy network traffic. – A subnet mask helps in separating an IP address into network and host address.
Why does IP address need subnet mask?
We need a subnet mask for IPv4 addresses because the address doesn’t give any information on the network size. Class sizes are not the network sizes. In practical networks all IPv4 networks are broken up into subnets that are smaller than the class size.
Can devices with different subnet masks communicate?
If two computers are on different networks, they have a different subnet mask and they can’t communicate to each other, unless connected by a router.
Can different subnet masks communicate?
A subnet is just a range of IP addresses. All the devices in the same subnet can communicate directly with one another without going through any routers.Suppose my IP address is 192.168. 101.15 and my subnet mask is 255.255.
Can you use any subnet mask?
However, an office network may be configured with a different subnet mask such as 255.255. 255.192, which limits the number of IP addresses to 64. Large networks with several thousand machines may use a subnet mask of 255.255. 0.0.
How do I fix IP subnet?
255.248 or /29.
- Step 1: Convert to Binary.
- Step 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask.
- Step 3: Find Host Range.
- Step 4: Calculate the Total Number of Subnets and.
What is mask in IP address?
A Netmask is a 32-bit “mask” used to divide an IP address into subnets and specify the network’s available hosts. In a netmask, two bits are always automatically assigned.225.0, “0” is the assigned network address. In 255.255. 255.255, “255” is the assigned broadcast address.
Can I change the subnet mask on my router?
On the router’s web admin interface, look for an advanced settings category called LAN. In it, go to the LAN IP settings section or tab, and change the value of the Subnet Mask with the one you want. Click or tap on Apply, Save, or OK.
