How do I find the DHCP address range?
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.
What was the old Class A IPv4 range?
0.0.0.0 to 127.255
Of the, two available IP protocol versions—IPv4 and IPv6—IPv4 is by far the most widely used today. It was originally organized into classes: Class A (0.0. 0.0 to 127.255.
How do you calculate IP range from subnet mask?
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 class A network range?
Class A Public & Private IP Address Range Class A addresses are for networks with large number of total hosts. Class A allows for 126 networks by using the first octet for the network ID. The first bit in this octet, is always zero. The remaining seven bits in this octet complete the network ID.
