Enhanced caching of domain name system (DNS) and reverse DNS queries for traffic management for signaling optimization in a mobile network

A method for enhanced domain name system (DNS) caching, the method comprising:

• at a server communicatively coupled between a wireless network and a DNS server:
• storing a DNS record in a local cache, wherein the DNS record comprises a hostname, a first IP address, and a first time-to-live (TTL) value;
• transmitting a query, associated with the DNS record, to the DNS server;
• receiving a response, associated with the query, comprising a second IP address and a second TTL value;
• determining the second IP address is different than the first IP address;
• determining a third TTL value based on a status of a first mobile device;
• updating the DNS record with the second IP address;
• and
• transmitting the second IP address and the third TTL value to the first mobile device on the wireless network, wherein the first mobile device updates a corresponding DNS record with the second IP address and the third TTL value that is greater than the second TTL value.
