Disproportionation redox reaction.

Reason: N in NO2 has oxidation state +4. In the products one N is oxidized to +5 in NO3− and another is reduced to +3 in NO2−, so the same species (NO2) is both oxidized and reduced. (You can show half‑reactions to confirm they combine to give 2NO2 + 2OH− → NO3− + NO2− + H2O.)
