About DNSc

µC/DNSc is compliant with the all DNS server. It was written for target systems running µC/TCP-IP and an OS such as µC/OS-II or µC/OS-III.

Asynchronous / non-blocking mode	µC/DNSc can be configured to run in his own task and to allow non-blocking calls. It can also be configured to be always in blocking mode to reduce the memory footprint.
Cache	A built-in cache is included. The number of cache entries is configurable to contain only what is required and minimize memory footprint.
Run-time configurable	All parameters used by µC/DNSc are run-time configurable. A minimum set of parameters are used a the compile-time to set the mode to minimize memory footprint.
