Subnet calculator allows calculation for Host Bits. Subnet bits are the number of bits used to identify subnet. IP network is divided into network prefix and host identifier. Host bits are there to identify hosts and it is divided into subnet and host identifier.

Using /31 ( gives you two addresses per subnet. You use them both as hosts. The drawback is that broadcasts are limited. Here's the official Cisco take on it: "RFC 3021 describes using 31-bit prefixes for point-to-point links. This leaves 1 bit for the host-id portion of the IP address. At one point a /31 subnet mask would be illegal, since the reserved "all zeroes" and "all ones" addresses would use up the entire "address space" of the one bit of host address. In December 2000, RFC 3021, Using 31-Bit Prefixes on IPv4 Point-to-Po
