Interesting days as always. Recently I was handed over “Alumni form” from college.
Mixed feelings. This brings me to conclusion that I somewhat missed college life but anyways that’s small price I paid for my high obsession with some long term ideas. (ok may be that explains why I don’t have a Facebook account? Stop asking me about it!)
Hard to come to any conclusion at this stage.
Anyways post for today…
Finally back in village location.
Was just looking around and saw BSNL having really crazy routing. I looked around and saw this:
NIXI Looking Glass - show ip bgp neighbors 218.100.48.15 routes
Router: NIXI Delhi (Noida)
Command: show ip bgp neighbors 218.100.48.15 routes
Total number of prefixes 0
Clearly BSNL is NOT announcing any prefix at NIXI Delhi at all. Thus if one has to send packets to BSNL in North area either it will be via transit (Tata/VSNL) or via any other peering NIXI exchange in Mumbai or Chennai.
Super dull time here. No classes going on due to “TCS Placement session” at college and this makes me to sit in my room most of time of my day.
Yesterday I tested connectivity to all 13 Global Root DNS Servers and found i root was giving issue.
Here’s a my yesterday’s traceroute to i root:
traceroute to i.root-servers.net. (192.36.148.17), 30 hops max, 60 byte packets

Since i root is another root server hosted within India by NIXI, I was quite sure this was issue again due to NIXI’s regional route enforcement policy along with missing transit link on i root. You can see my last blog post about same issue with F root here.
Time for a quick followup blog post. On 26th April of this year I blogged about broken connectivity of F root server which was hosted in NIXI Chennai. Apart from that blog post, I did informed ISC which operates F root (NIXI was host on behalf of them in India). In my open email on APNIC mailing list, I got a reply from Network Operations Center of ISC that they will verify and will take necessary action. Within 48 hours of that email they figured out root cause and since they couldn’t fix it right at that point, they pulled plug off from that root server.
NIXI i.e National Internet Exchange of India is well known for it’s inefficiency and for its bad policies. I am posting this blog post to discuss some of them.
NIXI is one (and only) Indian IXP i.e Internet Exchange Point established in 2003 so as to facilitate peering between Indian ISPs. Before this, there were lot of cases when Indian ISP’s were connecting to each other from outside India in Singapore and Europe. Thus NIXI established few exchanges in key cities where necessary infrastructure was provided to ISP’s to “peer”. With peering, the strict technical meaning is that exchange of traffic between ISPs.
