Private IP getting routed over Internet
- by WernerCD
We are setting up an internal program, on an internal server that uses the private 172.30.x.x subnet... when we ping the address 172.30.138.2, it routes across the internet:
C:\>tracert 172.30.138.2
Tracing route to 172.30.138.2 over a maximum of 30 hops

Trace complete.
This has a number of us confused. If we had a VPN setup, it wouldn't show up as being routed across the internet. If it hit an internet server, Private IP's (such as 192.168) shouldn't get routed.
What would let a private IP address get routed across servers? would the fact that it's all comcast mean that they have their routers setup wrong?
