Ping response time

Hello,
I have few servers that respond to ping and have response time over 200ms. Can it be an issue and is it something that we need to be concerned with? If yes, what would we need to do in order to improve the response time?

IPV4Address      ResponseTime
10.48.126.18      3681
10.50.44.84      269
10.48.92.15      193
10.42.28.34      95
10.42.60.17      60
10.48.252.17      59
10.56.240.17      53
10.63.132.15      39
10.48.140.15      30
10.42.176.15      28
10.56.170.15      27
10.35.21.243      12
10.35.21.31      2

THank you very much.

Are the servers local or over a VPN?

Local ping time for me is 1 ms. Your times are long for local.

Please describe the setup a bit.

Thank you John!
The servers are local too but we host DNS somewhere else. So we don't manage DNS in house. So, what we do is just put the DNS servers in TCP/IP settings. Should we be concerned that the ping response time is so large?

Is this issue with hosted DNS?

Let me know.

I don't think that it would be DNS since you are pinging the IP address and not the servername so there is no name resolution. I do recommend local DNS though. Are you experiencing any other performance issues with these servers?

I just pinged my own home computer across the internet over a secure permanent tunnel from where I am and got 70 ms average. Just a reference point.

If you're interested in what's "typical", you might traceroute a few well-known sites to see the results *per hop*.

Thank you all for great answers! Hosted DNS is the problem. But you also helped with the details on how to troubleshoot and find out what what is the issue.

I do netpipe for latency and ping for packet loss, notice: Latency , Loss and Jitter, these parameters mainly depend on the Quality and utilization of the links

This has nothing to do with DNS. You are pinging the IP address. If your ping ms is high this is typically an issue with the routing path that it is taking to get to the destination.

Another thing it could be is the router at the site where you are pinging the machine. Might need to be rebooted etc.

DNS is also recommended to be local (if possible) however having DNS over a site-to-site VPN it possible with very little overhead.

Put this in perspective, I have a site in Candada and another site in Vietnam and my ping ms to Vietnam data center is about 300ms. So that is over about 15 hops. When you are getting 300+ ms and it is not geographically far away it is usually due to a routing issue or a router malfunction.
