Methods for managing network connections based on DNS data and network policies and devices thereof

A non-transitory computer readable medium having stored thereon instructions for managing network connections based on DNS data and network policies comprising executable code which when executed by one or more processors, causes the processors to:

• determine when an obtained domain name identifies a trusted service and an obtained destination IP address is included in a current host IP address list;
• replace the obtained destination IP address with a new IP address from the current host IP address list when the obtained domain name is determined to be present and the obtained destination IP address is determined to be absent from the current host IP address list;
• and
• manage a received request based on a network policy comprising providing a client access to the trusted service identified by the obtained domain name hosted at the replaced new IP address.

A network traffic manager apparatus, comprising memory comprising programmed instructions stored in the memory and one or more processors configured to be capable of executing the programmed instructions stored in the memory to:

• determine when an obtained domain name identifies a trusted service and an obtained destination IP address is included in a current host IP address list;
• replace the obtained destination IP address with a new IP address from the current host IP address list when the obtained domain name is determined to be present and the obtained destination IP address is determined to be absent from the current host IP address list;
• and
• manage a received request based on a network policy comprising providing a client access to the trusted service identified by the obtained domain name hosted at the replaced new IP address.

A network traffic management system, comprising one or more traffic management apparatuses, client devices, or server devices, the network traffic management system comprising memory comprising programmed instructions stored thereon and one or more processors configured to be capable of executing the stored programmed instructions to:

• determine when an obtained domain name identifies a trusted service and an obtained destination IP address is included in a current host IP address list;
• replace the obtained destination IP address with a new IP address from the current host IP address list when the obtained domain name is determined to be present and the obtained destination IP address is determined to be absent from the current host IP address list;
• and
• manage a received request based on a network policy comprising providing a client access to the trusted service identified by the obtained domain name hosted at the replaced new IP address.
