When you pull the address from an interface, it's of type *net.IPnet wrapped in a net.Addr interface, which contains and address and netmask not an address and port. You can use the IP address however to create a new TCPAddr after asserting it as a *net.IPnet

    ief, err := net.InterfaceByName("eth1")
    if err !=nil{
            log.Fatal(err)
    }
    addrs, err := ief.Addrs()
    if err !=nil{
            log.Fatal(err)
    }

    tcpAddr := &net.TCPAddr{
        IP: addrs[0].(*net.IPNet).IP,
    }
