What is the default mask of the following address?
Most home networks use the default subnet mask of 255.255. 255.0. 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.
What is the default mask of Class A IP address?
255.0.0.0
Class A networks use a default subnet mask of 255.0. 0.0 and have 0-127 as their first octet.
What are the default masks for each network class?
Default Subnet Mask
| IP Address Class | Default Subnet Mask |
|---|---|
| Class A | 255.0.0.0 |
| Class B | 255.255.0.0 |
| Class C | 255.255.255.0 |
How is address mask calculated?
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.
Which IP address is a unicast address of a default subnet mask is used?
45.255 are Class C addresses. With the default subnet mask of 255.255. 255.0, 192.16. 43.67 is a unicast address or host address, 195.124.
What is the default IP address class available?
IP Address default subnet masks
| Class | Range First Octet | Default Subnet Mask |
|---|---|---|
| A | 1-127 | /8 255.0.0.0 |
| B | 128-191 | /16 255.255.0.0 |
| C | 192-223 | /24 255.255.255.0 |
| D | 224-239 |
How do I check my IP for free?
Running ipconfig on a Windows PC
- Click the Start menu.
- In Search/Run bar, type cmd or command, then press Enter.
- In the Command Prompt, type ipconfig or ipconfig/all, then press Enter.
- Using the available IP range determined by your router, run a ping command to an address in that range to confirm it is free for use.
Which is the default subnet mask for an IP address?
Thus, the subnet mask for this default case has 1s for the network ID portion and 0s for the host ID portion. This is called the default subnet mask for each of the IP address classes.
Which is the default mask for Class C?
Class C – 255.255.255.0 Example : Given IP address 132.6.17.85 and default class B mask, find the beginning address (network address). Solution : The default mask is 255.255.0.0, which means that the only the first 2 bytes are preserved and the other 2 bytes are set to 0.
What is the mask in the address block?
Mask – It is a 32-bit binary number that gives the network address in the address block when AND operation is bitwise applied on the mask and any IP address of the block. The default mask in different classes are :
How are host IDs represented in broadcast address?
Broadcast address : By putting the host bits as 1 and retaining the network bits as in the IP address 4. Number of hosts per subnet : 2 (32 – Given bits for mask) – 2 5. First Host ID : Subnet address + 1 (adding one to the binary representation of the subnet address)
