network_size: Network size

In ipaddress: Data Analysis for IP Addresses and Networks

Network size

Description

network_address() and broadcast_address() yield the first and last addresses of the network; num_addresses() gives the total number of addresses in the network.

Usage

network_address(x)

broadcast_address(x)

num_addresses(x)

Arguments

x	An ip_network vector

Details

The broadcast address is a special address at which any host connected to the network can receive messages. That is, packets sent to this address are received by all hosts on the network. In IPv4, the last address of a network is the broadcast address. Although IPv6 does not follow this approach to broadcast addresses, the broadcast_address() function still returns the last address of the network.

Value

• network_address(): An ip_address vector

• broadcast_address(): An ip_address vector

• num_addresses(): A numeric vector

See Also

Use seq.ip_network() to generate all addresses in a network.

Examples

x <- ip_network(c("192.168.0.0/22", "2001:db8::/33"))

network_address(x)

broadcast_address(x)

num_addresses(x)
