Functions ¶
func BigtoHWAddr ¶
BigtoHWAddr convert n to a hardware address, with specified alen
func BigtoMACAddr ¶
func BigtoMACAddr(n *big.Int) (net.HardwareAddr, error)
BigtoMACAddr convert n to a MAC address
func GenAddrWithIPNet ¶ added in v0.1.2
GenAddrWithIPNet geneate an address = prefix + hostn. hostn must>=0
func GenConnectionAddrStr ¶
GenConnectionAddrStr return a string with following format: IPv4: <prefix><ip>:<port> IPv6: <prefix>[<ip>]:<port>
func GenPrefixWithPrefix ¶ added in v0.1.3
GenPrefixWithPrefix geneate an prefix = prefix + hostn. hostn must>=0
func GetLLAFromMac ¶ added in v0.1.1
func GetLLAFromMac(mac net.HardwareAddr) net.IP
GetLLAFromMac return an IPv6 link local address from mac, based on Appendix A of RFC4291
func HWAddrtoBig ¶
func HWAddrtoBig(addr net.HardwareAddr) *big.Int
HWAddrtoBig convert hardware address to *big.Int
func IncMACAddr ¶
func IncMACAddr(macaddr net.HardwareAddr, step *big.Int) (net.HardwareAddr, error)
IncMACAddr increase macaddr by step (could be negative), return the result
