Constants ¶
const IPv4RE = "((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)[.]){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)"
IPv4RE is a regular expression that will match an IPv4 address.
const ReservedCIDRDescription = "Reserved Network Address Blocks"
ReservedCIDRDescription is the description used for reserved address ranges.
Variables ¶
var LocalAddr net.Addr
LocalAddr is the global option for specifying the network interface.
var ReservedCIDRs = []string{
"192.168.0.0/16",
"172.16.0.0/12",
"10.0.0.0/8",
"127.0.0.0/8",

"192.12.109.0/24",
"192.31.196.0/24",
"192.0.0.0/29",
}
ReservedCIDRs includes all the networks that are reserved for special use.
Functions ¶
func AllHosts ¶
AllHosts returns a slice containing all the IP addresses within the CIDR provided by the parameter. This implementation was obtained/modified from the following: https://gist.github.com/kotakanbe/d3059af990252ba89a82
func CIDRSubset ¶
CIDRSubset returns a subset of the IP addresses contained within the cidr parameter with num elements around the addr element.
func DialContext ¶
DialContext performs the dial using global variables (e.g. LocalAddr).
func IsReservedAddress ¶
IsReservedAddress checks if the addr parameter is within one of the address ranges in the ReservedCIDRs slice.
func Range2CIDR ¶
Range2CIDR turns an IP range into a CIDR.
