Who's running gopher on IPv6?! | |
April 10th, 2018 | |
---------------------------------------- | |
Using some (not so creative) command line tools, I have come up with a | |
partial list of gopher servers that use IPv6... As a starting point I | |
used Cameron Kaiser's list of new gopher servers since 1999 (which only | |
has stable servers with DNS, hence the list being partial), and then | |
ran an nslookup for AAAA records... | |
The commands I used went something like this: | |
curl -s gopher://gopher.floodgap.com:70/1/new | sed 's/,/XXX/' | \ | |
tr "\\t" "," | dos2unix | grep '^1' | awk -F, '{print $3}' | \ | |
sed '/^\s*$/d' | grep --color=never -E '(.*\.){1}' | sort | uniq > \ | |
gopher.servers.txt | |
nslookup << EOF > gopher.AAAA.txt | |
set querytype=AAAA | |
$(cat gopher.servers.txt) | |
exit | |
EOF | |
I could easily have done this with more portable commands and condensed | |
them down to use less total commands, but I was in a hurry. :) | |
BTW, the gopher RFC says to use FQDN only for the hostname portion of | |
a gopher resource, so the bare IP lines below probably wont work: | |
