ipv4-subnet-calculator-perl

Network calculator for subnet mask and other classless (CIDR) network information.

Features

Given an IP address and CIDR network size, it calculates the network information and provides all-in-one aggregated reports.

Calculations

• IP address network subnet masks, network and host portions, and provides aggregated reports.
• Subnet mask
• Network portion
• Host portion
• Number of IP addresses in the network
• Number of addressable hosts in the network
• IP address range
• Broadcast address Provides each data in dotted quads, hexadecimal, and binary formats, as well as array of quads.

Aggregated Network Calculation Reports

• Hash
• JSON
• String
• Printed to STDOUT

Usage

Create New Net::Subnet_Calculator Object

# For network 192.168.112.203/23
my $sub = Net::Subnet_Calculator->new( '192.168.112.203', 23 );

Get Various Network Information

my $number_ip_addrssses = $sub->get_number_ip_addresses();    # 512
my $number_hosts = $sub->get_number_addressable_hosts();    # 510
my ( $lower, $upper ) = $sub->get_ip_address_range();    # ( 192.168.112.0, 192.168.113.255 )
my $network_size = $sub->get_network_size();    # 23
my $broadcast_address = $sub->get_broadcast_address();    # 192.168.113.255

Get IP Address

my $ip_address = $sub->get_io_address();    # 192.168.112.203
my @ip_address_quads = $sub->get_ip_address_quads();    # ( 192, 168, 112, 203 )
my $ip_address_hex = $sub->get_ip_address_hex();    # C0A870CB
my $ip_address_binary = $sub->get_ip_address_binary();    # 11000000101010000111000011001011

Get Subnet Mask

my $subnet_mask = $sub->get_subnet_mask();    # 255.255.254.0
my @subnet_mask_quads = $sub->get_subnet_mask_quads();    # ( 255, 255, 254, 0 )
my $subnet_mask_hex = $sub->get_subnet_mask_hex();    # FFFFFE00
my $subnet_mask_binary = $sub->get_subnet_mask_binary();    # 11111111111111111111111000000000

Get Network Portion

my $network = $sub->get_network_portion();    # 192.168.112.0
my @network_quads = $sub->get_network_portion_quads();    # ( 192, 168, 112, 0 )
my $network_hex = $sub->get_network_portion_hex();    # C0A87000
my $network_binary = $sub->get_network_portion_binary();    # 11000000101010000111000000000000

Get Host Portion

my $host = $sub->get_host_portion();    # 0.0.0.203
my @host_quads = $sub->get_host_portion_quads();    # ( 0, 0, 0, 203 )
my $host_hex = $sub->get_host_portion_hex();    # 000000CB
my $host_binary = $sub->get_host_portion_binary();    # 00000000000000000000000011001011
