ipsubnet

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
