We calculate electric and magnetic masses of gluons between T = T_c and 6T_c using lattice QCD (quantum chromodynamics) in the quench approximation. We find that magnetic mass has finite values in this region, and the temperature dependence of the electric mass is consistent with that determined using the hard-thermal-loop perturbation. The hard-thermal-loop resummation improves significantly the magnitude of the electric mass comparing to the leading order perturbation. Both screening masses have little gauge dependence.
