Does ping use nslookup?
nslookup consults only the DNS server configured, while ping -a uses additional methods like NETBIOS to resolve the name. If both computers are in the same network segment, they use broadcast messages to exchange host names without a DNS server, so ping -a works and nslookup doesnot.
Does ping use DNS cache?
The Ping Monitor in PA Server Monitor uses the Windows API WSAStringToAddress to resolve addresses, which works like ping -4, meaning it uses the internal Windows DNS cache. So if you want to test that a name resolves with DNS, it is best to use the DNS Monitor instead of the Ping monitor.
Why does ping and nslookup return different IP?
ping is using the cached response from the lookup against the external DNS server, while nslookup sends a fresh request that gets a valid response from your internal DNS server. Having inconsistent views of DNS between your primary and secondary servers is bound to cause problems like this.
Why can’t I ping my DNS server?
It is very possible that your DNS server is firewalled and is blocking ICMP ping requests. If it is doing DNS lookups according to your nslookup command, then your DNS server is working fine.
How does ping resolve hostnames Windows?
ping –a does not ask the DNS server to resolve a name. A “ping –a” is always answered by the local DNS cache (DNS client service) only. -t repeats the ping command until stopped by the user with Ctrl-c. Depending on your network configuration, you can use values between 1500 and 65000.
What does ping resolve hostnames do?
Hostnames are still resolved through DNS, after that ping uses ICMP for the actual communication.
Is it possible to ping yourself?
When you ping your IP address, you ping yourself, but it goes through those drivers for that network card first, or at least can. Implementations of this behavior do in fact vary from system to system, but that’s conceptually how it works. Also, you won’t notice a time difference, as both of them are extremely fast.
How do I check if my DNS is resolving?
To see your current DNS settings, type ipconfig /displaydns and press Enter. To delete the entries, type ipconfig /flushdns and press Enter. To see your DNS settings again, type ipconfig /displaydns and press Enter. You should see blank records or you might get the message “Could not display the DNS Resolver Cache.”
Why was my ping answered by a different IP address than the one pinged?
If your subnet mask were configured incorrectly, the router might respond to the ping. What was the subnet mask you were given? Show activity on this post. If you have a network admin assigning IP addresses, the same network admin should be able to troubleshoot the response.
Can ping but not nslookup?
If nslookup works but ping fails, it’s possible that the hosts’ file was edited by malware or another application, and that can cause this and similar problems to appear. To fix the problem, it’s advised to check this file and make sure that everything is in order.
