IPv6 Targets
One can use https://network-tools.webwiz.net/ping.htm to check if a target responds to IPv6 pings. As part of this we discovered that the SLAC border was blocking IPv6 pings (see INC0178575).
XML file at Guanhzhou
See here. Currently, it contains random pingable IPv6 addresses as Saqib took it from http://www.ipv6forum.com/ipv6%5fenabled/approval%5flist.php. He proceeded as follows:

There is a spreadsheet of active landmarks that can make pings 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.
In the spreadsheet there is a column labelled Ping URL. It contains the URL of the ping server for the Measurement Agent (MA).
We wrote a perl script ping-ipv6-ps.pl to ping all those IPv6 addresses from an IPv6 host at SLAC and none responded to an IPv6 ping. The config file is /u/sf/cottrell/ps-lm.csv obtained by exporting the active landmarks.
East Carolina University listEast 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 list of about 1000 world universities and their IPv6 addresses if they have them. About their IPv6 addresses if they have them. It uses IT sonar agents from Nephos6, to perform "user experience" measurements accessing select websites from multiple global geographic vantage points. 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).
SLAC IPv4 Pinger hosts
Using %NODE_DETAILS we wrote a script ping-ipv6-pinger.pl to identify (using dig hostname AAAA) whether the host has an IPv6 address and if so try and ping it with ping6.
