How Do I Find My Subnet Mask For Class B?

2-2=510 subnets. 2-2=126 hosts per subnet. For the third octet, the mask would be 256-255=1, 2, 3, 4, 5, 6, etc. For the fourth octet, the mask would be 256-128=128, which is one subnet if it is used.

How do I find my IP address and subnet mask?

IPv4 addresses are 32 bits made up of four octets of 8 bits each. To calculate the subnet mask, convert an IP address to binary, perform the calculation and then convert back to the IPv4 decimal number representation known as a dotted quad. The same subnetting procedure works for IPv6 addresses.

How do I find my subnet mask on my phone?

You can check the subnet mask value.
Configuring/Checking DHCP services (Android device)

1. Tap [DNS server].
2. Select [Manual] on the select screen. [Auto] is selected normally.
3. Enter the necessary DNS server.
4. Tap [OK] to complete the settings.

How do you find a subnet class?

You can identify the class of an IP address by looking at its first octet. Following are the ranges of Class A, B, and C Internet addresses, each with an example address: Class A networks use a default subnet mask of 255.0. 0.0 and have 0-127 as their first octet.

What is network ID and subnet mask?

A subnet mask is a four-octet number used to identify the network ID portion of a 32-bit IP address. A subnet mask is required on all class-based networks, even on networks that are not subnetted.

Which address class does not need subnet mask?

0.0 to 255.255. 255.255. Just like our Class D multicast addresses, these addresses do not have a default subnet mask.

What is subnet in IP address?

A subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to the same subnet are addressed with an identical most-significant bit-group in their IP addresses.

How do I find my IP address subnet mask and default gateway on Android?

How to Find Default Gateway IP Address on Android?

1. Tap Settings.
2. Tap Wi-Fi.
3. Long tap your network connection.
4. Tap Modify network.
5. Tap Advanced options.
6. Switch the IPv4 settings to Static.
7. Find your gateway IP address listed next to Gateway.

What is subnet mask on router?

A subnet mask is a number that defines a range of IP addresses available within a network. A single subnet mask limits the number of valid IPs for a specific network.Systems within the same subnet can communicate directly with each other, while systems on different subnets must communicate through a router.

What is the default subnet mask of Class B?

255.255.0.0
Consequently, the default subnet mask for Class B is 255.255. 0.0. In addition, Class C IP addresses are normally assigned to a very small-sized network. Their IP addresses range from 192 to 233 and their default subnet mask is 255.255.

How many addresses are there in a class B subnet?

Class B Address
x.x. The default subnet mask for Class B is 255.255. x.x. Class B has 16384 (2¹⁴) Network addresses and 65534 (2¹⁶-2) Host addresses.

How do I find subnet ID?

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. The result is the subnet address in which the host is situated.

What are the 3 classes of subnet mask?

Class A, B, and C networks have natural masks, or default subnet masks:

• Class A: 255.0. 0.0.
• Class B: 255.255. 0.0.
• Class C: 255.255. 255.0.

What is the default subnet mask?

The three default subnet masks are 255.0. 0.0 for Class A, 255.255. 0.0 for class B, and 255.255. 255.0 for Class C.

How do I find my subnet mask Mac terminal?

Click the Apple icon and open System Preferences -> Network. From the Location drop-down list, select Automatic and select your Ethernet connection or Airport if you are connect to the Wi-Fi.

How do I find my default gateway IP address?

Most Android devices

1. Go to Settings.
2. Under Wi-Fi, tap your current active Wi-Fi network.
3. Tap Advanced. Your default gateway’s IP address will appear under Gateway.

How do I find my gateway IP address?

If subnet mask is 255.255. 255.248 then number of masked bit will be 5, hence number of subnets = 2. The power number of masked bits = 2 the power 5 = 32 subnets, and the number of hosts per subnets = 2. The power (unmasked bit or 32- total number of network bits) = 2 the power (32-29) = 8 host/subnet.

Can I change my subnet mask?

When do we change a Subnet Mask? If you have an address range that has run out of available host addresses, you may be able to change the subnet mask to include a larger share of host addresses.
