description Methods, systems, and non-transitory computer readable media for enhanced domain name system (DNS) caching are disclosed. According to one aspect, a method for enhanced DNS caching includes, at a mobile device for operating in a wireless network, providing, within the mobile device, a local DNS cache that stores DNS-related queries and their respective responses received from a DNS server for responding to DNS-related queries issued from applications hosted within the mobile device, where each response received from the DNS server is associated with a first time-to-live (TTL) value for that response, and assigning to each query/response pair in the local DNS cache a second TTL value that is larger than that response's first TTL value, where the second TTL value is used in place of the first TTL value.
