IPv6 Targets
XML file at Guanhzhou
See here. Currently, it contains random pingable IPv6 addresses as I have taken Saqib took it from http://www.ipv6forum.com/ipv6%5fenabled/approval%5flist.php. He proceeded as follows:
- I am trying to make a list of IPv6 pingable sites of the education institutes of the world. For this, I have taken the list of top 1000 universities of the world (http://cwur.org/2017.php)
- Next I am validating each site on http://ipv6-test.com/validate.php for AAAA record.
- When I get the IPv6 address, I checked its ping status on https://network-tools.webwiz.net/ping.htm . Currently, I do not have a direct access to IPv6 machine.
- If the address is pingable, I add its details in the attached excel sheet.
- Latitude and Longitude are calculated using https://www.iplocation.net/index.php
- I have added few sites in the attached file. However, I am facing problems in finding Lat/log of the server as it seems that they are not located on the campus of the University. Kindly check the remarks column of the US universities.
perfSONAR
Unfortunately it is very common that sites use a proxy for common services such as www. A possibility is to use perfSONAR. These are high performance throughput monitoring sites mainly in US, and Europe. perfSONAR fully supports IPv6 and has a data base that includes latitude and longitude. When we were working on TULIP ( the use of pings from ping servers to find the location of targets) we used these perfSONAR ping/traceroute servers/landmarks to make the RTT measurements. There is some documentation at https://confluence.slac.stanford.edu/display/IEPM/Automated+PerfSONAR+Landmark+finding
There is a spreadsheet of active landmarks at http://www-wanmon.slac.stanford.edu/cgi-wrap/reflector.cgi?function=landmarks&ability=1. I am not sure how current this is, the psonar_auto.pl job updates the web page information and runs monthly. Tulip has not been maintained for a couple of years. There is more documentation at https://confluence.slac.stanford.edu/display/IEPM/TULIP+Analysis and looking at http://www-iepm.slac.stanford.edu/pinger/crontab-slaconly.txt you can see the tulip jobs that are run by cron.
East Carolina University list
Quality of IPv6 Enablement of Universities: An International Study by John Pickard and Anne Y Patric of East Carolina University has a liist of about 1000 world universities and their IPv6 addresses if they have them. About 125 hosts have IP addresses. We wrote a perl script (ping-ipv6.pl) to ping all those IPv6 addresses from an IPv6 host at SLAC and none responded to an IPv6 ping. It runs against the file of ipv6 universities exported from the Excel spreadsheet as a tab delimited file (top-uni.txt).
