200M : What is the 10. local IP address?

[GazCBG]

Hi,

I just did a trace route and saw a high ms response on the 10. IP, is that the Hub or where the Hub connects to the VM network?


1 <1 ms <1 ms <1 ms router.asus.com [192.168.1.1]
2 288 ms 264 ms 250 ms 10.33.88.1
3 194 ms 210 ms 213 ms nott-core-2a-xe-210-0.network.virginmedia.net [62.255.214.129]

No, that is normally an internal IP.

That aside response times from intermediates on the route to the destination mean nothing. It is the response from the target IP that is important.

The organization that doles out IP addresses to the world reserves a range of IP addresses for private networks. Private networks can use IP addresses anywhere in the following ranges:
•192.168.0.0 - 192.168.255.255 (65,536 IP addresses)
•172.16.0.0 - 172.31.255.255 (1,048,576 IP addresses)
•10.0.0.0 - 10.255.255.255 (16,777,216 IP addresses)

The assumption is that these private address ranges are not directly connected to the Internet, so the addresses don't have to be unique. In today's world, these private address ranges are often used for the protected network behind network translation devices.

Because the private address ranges in a network don't have to be synchronized with the rest of the world, the complete address range is available from any network. A network administrator using these private addresses has more room for subnetting, and many more assignable addresses.

I am aware it is a local/private IP.
But neither or you answered my questions.

Does the 10. IP belong to the Hub or is it where the Hub connect to the VM network?
I would think the Hub does have a local/private IP on the VM network to send updates, etc...

Also I am not after the ms trace route ping for the full route, I am trying to work out where the issue is with my T3 and Upstream issues is.

The hub does not have an ip on the vm network for the purposes you describe. Ip is layer 3 and modems are layer 2. Modems and the vm network work on layer 2 which is mac addresses.
With regards to the 10. address, it is internal adressessing used by vm and in your specific example it is the ip of your cmts in vm's internal network which does not need a globally routable ip.

It is basically your internal ip on the vm network, as GM says, it belongs to your ubr.
