Described herein are methods and systems for improved domain name resolution/routing. Routing data associated with domain names (e.g., websites) may be cached by a Domain Name System (DNS) based on historical domain name queries. The historical domain name queries may be analyzed to determine a ranking (e.g., popularity) for the domain names at multiple time intervals throughout a day, week, etc. Routing data for the highest ranked domain names during one or more time intervals may be cached for a period(s) of time corresponding to the one or more time intervals (e.g., times during which those domain names are most popular).

Systems, methods, and apparatuses for improved domain name resolution

An encrypted message comprising a DNS request may be received from a client device. The DNS request may be decrypted to determine an IP address and a port associated with the client device. A security token may be determined based on the IP address and the port. A message comprising an indication of the DNS request and the security token may be sent to a DNS server. A reply comprising a payload and the security token may be received from the DNS server. Based on the security token, an indication of the payload of the reply may be sent to the client device.

Systems and methods for secure communication

A network device (e.g., a server, a domain name system (DNS) server, a DNS over Hypertext Transfer Protocol Secure (HTTPS) server (DoH server), a network management device, etc.) may determine a time duration, such as a time duration, based on a request for a communication session from a device. In response, the network device may determine a modified time duration for the communication session based on a type of the device, type of user associated with the device, and/or type of an application requesting the communication session.
