Noticed today while doing some plotting for your other thread that I am getting different ip's listed enroute when i run a ping and compare the results with a traceroute.
Normal ?
If this is not normal then who should i be blaming :D
-
Nope not normal. The router IPs from you to HTC should remain constant. Mine change at both Savis and Level3 on my pingplots.
-
I would like to see some comparison traces showing this phenomenon. I would also need the precise time each was run.
EDIT: Nevermind. I saw what you are talking about. It all depends on if the IP address is just another IP address to the same interface or not. Routers are fun that way.
-
Just to be clear.
If i run pings and tracert to the same ip (MA).
All the ips listed seem to be different until the target.
IE ping -r 9 to 216.91.187.39

Another related question. How do we know if its the same router with a different port/interface?
Example: an IP address is A.B.C.D if the D varies I'd assume its the same router. Is it still ok if both C and D change?
Does the DNSName have to change for it to be considered 'wacked'?
