IPv6 DNS Measurement Stats

NIC IPv6 DNS Measurement
Measuring who all are querying for nic.in or gov.in domain, what they are querying for and from where they are querying.

NIC had tested its IPv6 connectivity with internet peers on June 8, 2011 (World IPv6 day) and next year on World IPv6 Launch Day (June 6, 2012), we had launched our IPv6 DNS Server (having address 2405:8A00:1000::2) along with some websites.
 Our IPv6 DNS Servers are live from day one onwards and today we are receiving roughly 54000 queries per hour over IPv6 for various nic.in and gov.in domains.


In this paper, we are showing the following statistics:-

     1. Who all are querying us
    2. What they are querying for
    3.   From which part of world we are getting the hits

For taking out the bellow stats, we analyzed 7, 69, 00,000 (roughly 7.7 crore) IPv6 queries.



  

AS wise Query Statistics

Autonomous System number (ASn) wise query stat gives us the unexpected results. Although we were predicting that Google will be in top 3 but didn’t expect that half of received queries will be from Google only.


Google tops the list with 51.6% of queries and leads the list with huge margin. Facebook comes 2nd with 7.4% of total queries. Our own AS 4758 comes at 4th place.

Top 10 ASn

Most unpredictable and still unanswered behavior is having Facebook at number 2nd. I am still wondering why Fb is querying us and that too in that much quantity.
Our own ASn comes fourth after Google, Facebook and OpenDNS.  Only 2 organization from India find a place in this list. Apart from NIC only MTNL was able to reach in top 10.
This somehow shows that Indian Internet Users are using Open DNS Servers (like of Google, Hurricane and others).








Route wise Query Statistics

Route wise query stats also depicts the same pattern as that of ASn wise. Top 3 segment which queried us the most belongs to Google.











  
Most Queried Domain

India.gov.in tops in this list. It is the one which was queried maximum number of times over IPv6.


  Above graph depicts the top 10 third-level domains among *.nic.in and *.gov.in domain.

Availability of 5 GHz WLAN Channels in India under unlicensed band

Availability of 5 GHz WLAN Channels in India under unlicensed band  In India, Wireless Planning and Coordination Wing of Department of Telecom, under Ministry of Communication takes care of licensing of radio frequencies.  In the latest National Frequency allocation plan 2018 (https://dot.gov.in/sites/default/files/NFAP%202018.pdf), Government of India (GoI), exempted the licensing requirements of the following radio frequency ranges for wireless usage and a gazette notification has also published for this (https://dot.gov.in/sites/default/files/License%20Exemption%20in%205%20GHz%20G_S_R_1048%28E%29%20dated%2022nd%20October%2C%202018_0.pdf)  -- 1.  5150-5250 2. 5250-5350 3. 5470-5725 4. 5725-5875 References

Identity PSK ( iPSK)

With the evolution of IoT (Internet of Things), devices that connect wirelessly have increased many folds. From webcams, Smartwatches, fitness bands, firestick, Alexa, Google Home, and many more.., everything is going wireless for connectivity and so does the security threat. The main concern with IoT devices is the unavailability of the full wireless protocol stack (and in the majority of devices, support of 802.1x is not available). So, previously we only have the WPA-PSK option for connecting the IoT devices.  In WPA*-PSK (WPA or WPA2) WLAN, a Pre-Shared Key (PSK) is configured and distributed to all the clients that connect to the WLAN. This leads to PSK leakage, and it can be accessible to unauthorized users (due to the nature of common PSK across all the devices).  Therefore, there was a need to provision unique PSK or Multiple PSK per SSID. Identity-PSKs are unique pre-shared keys created for clients/groups on the same WLAN. Features of iPSK:-   1.Unique PSK for individual Cli

Summary report of APNIC 55 (APRICOT 2023) Meeting held in Manila, Philippines

APNIC Logo The APNIC 55 meeting was held in Manila, Philippines from 20th Feb to 02nd March 2023. The meeting was hosted by PhNOG, The Philippine Network Operators Group (PhNOG) and supported by DOST- Advanced Science and Technology Institute. Every year, APNIC conferences are held twice, the first of each year is held in conjunction with APRICOT and the second one is a standalone conference. The last such meeting held in India was in 2012, APNIC 33 (which was in conjunction with APRICOT 2012).  APNIC 55 meeting was unique in multiple senses –  i. Firstly, because of the possibility of potential hijack [1] [2][3] of the APNIC Executive Council by Cloud Innovation Ltd. / Larus foundation / NRS, the same organizations which have dragged AFRINIC (RIR for African Continent) into the Mauritius supreme court and at one point nearly halted the AFRINIC operations by getting its bank accounts frozen (over 25 lawsuits have been filed against AFRINIC by Cloud Innovation Ltd.).
