Hi,
I am a new member to this forum. I used traceroute utility at www.traceroute.org to trace routers between UCAL-Berkeley to google.
And I got the following trace. Can any body help me how I can identify what each hop is i.e. local(bet the institution), access(bet ISPs) or a backbone(bet tier 1 routers) hop
traceroute from www.net.berkeley.edu to www.google.com
