ipsubnet's Introduction

IPv4 Subnet Calculator (GO)

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

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.

Get Started

import "github.com/brotherpowers/ipsubnet"

sub := ipsubnet.SubnetCalculator("192.168.112.203", 23)

Get Network Information

sub.GetNumberIPAddresses();      // 512
sub.GetNumberAddressableHosts(); // 510
sub.GetIPAddressRange();         // [ 192.168.112.0, 192.168.113.255 ]
sub.GetNetworkSize();            // 23
sub.GetBroadcastAddress();       // 192.168.113.255

Get IP Address

sub.GetIPAddress();       // 192.168.112.203
sub.GetIPAddressQuads();  // [ 192, 168, 112, 203 ]
sub.GetIPAddressHex();    // C0A870CB
sub.GetIPAddressBinary(); // 11000000101010000111000011001011

Get Subnet Mask

sub.GetSubnetMask();       // 255.255.254.0
sub.GetSubnetMaskQuads();  // [ 255, 255, 254, 0 ]
sub.GetSubnetMaskHex();    // FFFFFE00
sub.GetSubnetMaskBinary(); // 11111111111111111111111000000000

Get Network Portion

sub.GetNetworkPortion();       // 192.168.112.0
sub.GetNetworkPortionQuads();  // [ 192, 168, 112, 0 ]
sub.GetNetworkPortionHex();    // C0A87000
sub.GetNetworkPortionBinary(); // 11000000101010000111000000000000

Get Host Portion

sub.GetHostPortion();       // 0.0.0.203
sub.GetHostPortionQuads();  // [ 0, 0, 0, 203 ]
sub.GetHostPortionHex();    // 000000CB
sub.GetHostPortionBinary(); // 00000000000000000000000011001011
