description A computing device receives an IP address extracted from an encrypted client hello (ECH) enabled transport layer security (TLS) connection request from a client computing device and identifies, from a list of a plurality of hostnames, a set of hostnames matching the IP address. The device generates a reduced list of the set hostnames matching the IP address and generates a reduced list of the set of hostnames matching the IP address by removing hostnames that do not support an ECH extension of a TLS standard from the set of hostnames matching the IP address. Finally, the device retrieves reputation information related to one or more hostnames of the reduced list for protecting the client computing device and/or a computer network based on the reputation information.
