Functions

func ParseAddress

func ParseAddress(s string) (net.IP, uint16, error)

ParseAddress parses a string, e.g., "0100007F:0050" (127.0.0.1:80) "000080FE00000000FF57A6705DC771FE:0050" ([fe80::70a6:57ff:fe71:c75d]:80) "00000000000000000000000000000000:0050" (0.0.0.0:80)

See https://serverfault.com/questions/592574/why-does-proc-net-tcp6-represents-1-as-1000

ParseAddress is expected to be used for /proc/net/{tcp,tcp6} entries on little endian machines. Not sure how those entries look like on big endian machines.
