WebAs the calculation above shows, there are a total of 512 IP addresses in a /23 block. However, one IP is a network address and another is a broadcast address. Therefore, the total number of useable IPs in a /23 can be calculated as follows: + 512 Total IP addresses - 1 Network IP address - 1 Broadcast IP address = 510 usable IP addresses WebThe smallest possible subnet is 4 IPs: a network number, 2 usable IPs, and an IP broadcast address.
