Beginning work on TUN interface And outbound routing I am not entirely convinced the use of net.IP is a good idea, since the internal representation of net.IP is a byte slice and all constructor functions in "net" return 16 byte slices (padded for IPv4), while the use in this project uses 4 byte slices. Which may be confusing. 2017-06-04 21:48:15 +02:00			`package main`
