Functions

func ArpScan

func ArpScan(iface *net.Interface, interval time.Duration, vendor *VendorFinder, result chan<- Device, ctx context.Context) error

ArpScan scans an individual interface's local network for machines using ARP requests/replies. scan loops forever, sending packets out regularly.

func GetAllIpAddressesWithinNet

func GetAllIpAddressesWithinNet(ipNetwork *net.IPNet) []net.IP

GetAllIpAddressesWithinNet computes all IPv4 addresses contained in net.IPNet
