  We characterize niobium nitride (NbN) $\lambda/2$ coplanar waveguide
resonators, which were fabricated from a 10nm thick film on silicon dioxide
grown by sputter deposition. For films grown at 120{\deg}C we report a
superconducting critical temperature of 7.4K associated with a normal square
resistance of 1k$\Omega$ leading to a kinetic inductance of 192pH/$\Box$. We
fabricated resonators with a characteristic impedance up to 4.1k$\Omega$ and
internal quality factors $Q_\mathrm{i} > 10^4$ in the single photon regime at
zero magnetic field. Moreover, in the many photons regime, the resonators
present high magnetic field resilience with $Q_\mathrm{i} > 10^4$ in a 6T
in-plane magnetic field as well as in a 300mT out-of-plane magnetic field.
These findings make such resonators a compelling choice for cQED experiments
involving quantum systems with small electric dipole moments operated in finite
magnetic fields.
