Day 16 of lockdown here in Haryana due to Covid19. Time for some distraction.

Last week it was reported that Wireguard will be added in next version of Linux kernel. I have been using Wireguard from over a year and it has been working great. I replaced OpenVPN with Wireguard for both site to site VPN as well as client-server VPN. If you are looking for a free open source VPN for remote employees or just connecting to your own remote servers Wireguard can be a really good candidate.

A fascinating lecture by Mr Anil Swarup (retired IAS, ex-Secretary to Govt. of India & State Govt of UP) at Lt Governer, Puducherry Raj Niwas. His Wikipedia page here and Twitter account here.

The first half is the talk itself, followed by some time of Q&A, followed by a short talk by Mr Ashwani Kumar (Chief Secretary to Government of Pondicherry) and in the end is Lt Governor Kiran Bedi.

In Melbourne for the week for APRICOT 2020. Someone jokingly said it’s should be “APRICOT and RPKI 2020”. :-)

It seems like both JPNIC and TWNIC are doing a good job at promoting their member operators in Japan & Taiwan for signing ROA. I thought to check for the status in India to find how India is doing.

RPKI ROA status for India

1. Total prefixes: 40,834 (IPv4 + IPv6)
2. Prefixes with valid ROA: 4693
3. Prefixes with invalid ROA: 354
4. Prefixes without ROA: 35,787

I had calls with a couple of friends over this week and somehow discussion IPv6 deployment came up. “How much has been IPv6 deployment in India now in 2020” is a very interesting question. It’s often added with - “how much of my traffic will flow over IPv6 once it is enabled”?

Game of numbers

There is a drastic difference in IPv6 deployment depending on which statistic we are looking at here in India. There can be a bunch of factors based on which we can try to judge IPv6 deployment:

A post to dump mind views. Hasgeek folks (who run RootConf conference in Bangalore + some other places around) seem to be in expanding mode. Besides RootConf which is a conference primarily for DevOps community, they are doing events on Fintech etc and now expanding to networks. I have been to and presented at multiple RootConfs on RIPE Atlas probes and BGP routing security. Both of these topics were from networking domain but closely touch the Sysadmins and thus probably made sense.

IRINN (Indian Registry for Internet Names and Numbers) is a NIR (National Internet Registry) for India operating under the APNIC RIR (Regional Internet Registry). IRINN is run and managed by NIXI. It’s a decent NIR and was set up in 2012. Indian organisations have the option to either maintain relation with APNIC or with IRINN.

A large number of small networks prefer IRINN because it’s annual charges are 25000 INR / $351 USD against APNIC’s membership fee which is over 2x of that.

A nice short 20mins video by VOX on how the internet works. It covers the basic idea of connectivity a higher level and I am probably going to pass this link to friends & family members outside of the networking domain when they ask. It also covers 60 Hudson Street which I visited exactly an year ago. :)

Hello world from Gujarat! This is my 3rd visit to Gujarat. :)

Coming to today’s post: I have noticed ISPs doing really crazy things to maximise traffic on peerings and IXPs. Some of those are bad and some are very bad. Additionally I came across this comment and thought to put this quick post.

Example of some bad ways to increase IXP traffic:

• Using upstream’s ASN to keep AS path shorter (yes, believe me I have seen that!)

Since last week of Nov 2019, I am having serious issues with Airtel at my home. Somehow 4G signal SNR is very poor and most of the calls just fail on that. Airtel support just mentioned that they are putting a new site in my area in Jan 2020 but fail to explain why suddenly it went so bad. I can imagine that support team staff does not have visibility to network in real-time and likely it would be an issue with the 4G antenna on one or more towers. 2G signal was good but latency was extremely high to connect call plus calls still failed regardless (maybe due to high strain on 2G).

Last week I visited Delhi and spent some time at the “Regulating for Inclusion” workshop. I usually do not attend non-NOG events but this one seemed interesting and was relatively easy to attend as was in Delhi.

Discussion on backhaul

There is quite a bit of talk as well as focus on the backhaul capacity but somehow discussion missed a very important element of the picture - Internet Exchange Points (IXP). Unless we have a vibrant number of exchanges and a broad sense to build & promote exchanges, we cannot really tap the Gig capacity of modern fibre to the home systems. In the absence of IXPs, we would end up in having a large part of interconnection in Mumbai, Chennai (and possibly Delhi, though Noida seems to be the case instead of Delhi). Imagine the amount of backhaul capacity we would need on the middle mile in these cases. Furthermore, traffic going out of region reduces the resiliency of the overall system in case of high-stress periods of natural disaster etc.
