Hi Dave, As u suggested I tried to retrive the DNS server IP and tried to query the ipNetToMediaTable. But in my DNS server the SNMP is not enabled.
Is there any way from which I can check if the SNMP is enabled on the remote device? Preferably C code. We are trying to discover the nodes in the subnet based on the list of MAC address given by the user. Currenty we are using the ICMP ping for the same, which takes a long time to retrive the information. So we are planning to do the same by querying the ipNetToMediaTable. This is required for us to reduce the time taken to map the MAC address versus IP.

It should have a relatively complete ARP cache, since any device that communicates with anything outside that subnet will need to go the router. So querying its ipNetToMediaTable might give you more information than a single random host would. Similarly, selected internal servers (e.g. a fileserver, or the DNS servers) may have a relatively complete record of IP-MAC mappings. Basically, think about what boxes everything else talks to. If they talk to it, then it should have an ARP record.
