he network address of 172.16.0.0/19 provides how many subnets and hosts?

The given network address is 172.16.0.0 with a subnet mask of /19. This means that the first 19 bits of the IP address are dedicated to the network portion, while the remaining bits are for host addresses within that network.

To understand how many subnets and hosts this provides, we need to break down the information:

1. CIDR Notation (/19): Classless Inter-Domain Routing (CIDR) notation of /19 means that 19 bits are used for the network part of the address. Since this is an IPv4 address, there are a total of 32 bits in the address. This leaves us with 32 – 19 = 13 bits for host addresses.

2. Calculating Subnets: Since the original classful nature of this address would be a Class B (given the starting range of 172.16.0.0), and Class B addresses typically come with a default subnet mask of /16, using a /19 subnet mask means we are subnetting further into smaller networks. The difference between the original class subnet mask (/16) and the given subnet mask (/19) is 3 bits (19-16 = 3). These 3 bits allow for 2^3 = 8 subnets. However, this calculation assumes we’re strictly adhering to subnetting within what would originally be considered a single network in classical classful networking. In modern classless networking, this isn
