IP calculator based on the number of hosts?

Question

Computer networks

There is a network 192.168.248.0/22
​​The initial host is clear, the final one is clear, the mask is clear, the maximum number of hosts is clear.
Now we need to create a DHCP Pool of addresses. For example, starting from 192.168.248.20, you need to add 857 addresses.
You can do it manually. Does anyone know a service where you can set the initial IP, add the required number of hosts to it, and get the final one in the given range?

Answer 1

Nobody adds "857 addresses", this is a flawed approach. Allocate a whole range, described briefly and clearly using CIDR . Otherwise, you will get tired of reading the configs of network hardware and software.

Answer 2

IP calculator .
