DNS resolver caches are the 'campus directory,' and when they store faulty information, traffic goes to the … ARP (Address Resolution Protocol) Spoofing is when an attacker sends out fake replies to an ARP Request. This is done usually to impersonate a router so that an attacker can intercept traffic.

The two processes are independent of each other. After you clear the DNS cache, the MAC address of the DNS server (or the default gateway, if the DNS server is on another network) can still be in the ARP cache, in which case, no ARP is necessary in order for your PC to communicate with the DNS server. 2017-09-28 · RP/0/ RSP0 /CPU0:router # show arp traffic ARP statistics: Recv: 2691 requests, 91 replies Sent: 67 requests, 2 replies (0 proxy, 1 gratuitous) Resolve requests rcvd: 1 Resolve requests dropped: 0 Errors: 0 out of memory, 0 no buffers ARP cache: Total ARP entries in cache: 4 Dynamic: 3, Interface: 1, Standby: 0 Alias: 0, Static: 0 IP Packet drop count for node 0/0/CPU0: 1 When a system call is made to a DNS Hostname, the request is first passed through DNS to get the IP Address for the Hostname.
