ABMJR.........how to find out ubr IP adresses?

c:>tracert yahoo.com
the first 10.x.x.x, this is the ubr ip

I knew that command before. It's just at one point in the past, just be shear luck I found one ubr IP hidden among the public IP's. And I didn't wrote it nowhere and I forget it.
I'm 100% sure it was ubr because of the my isp configuration.

you can find ALL your ISP UBR´s, if you know the cumunity string. I use the SolarWinds IP Network Browser
