mercutiowhy does everyone tell me to traceroute 216.81.59.173? [14:38]

mike-burnsmercutio: Because the Reddit hivemind finds it interesting this week. [14:41]
mercutiostatic: it's everywhere though
i've seen it what one .. two three four five places so far?
[14:41]
staticsafecorrect [14:42]
mercutiothen i scrolled back in here [14:42]
staticsafeit went viral [14:42]
mercutioand someone had mentioned it [14:42]
staticsafethere is a IPv6 one too
traceroute6 -m 120 tng.prolixium.com
[14:42]
mercutioem0.dax.prolixium.net
that's repeated a lot
[14:44]
staticsafeoh damn its down
it was working this morning
[14:44]
mercutiomaybe they needed their ipv6 addrresses back [14:44]

mercutiohmm
now i want something that shows different traceroutes to diff people
which would require doing it dynamically
and using ipv6 ;)
oh hmm, maybe you could do a reverse traceroute in the traceroute
and stick that in the dns'
you'd need some kind of trigger
and then to have the dns server delay giving responses until the traceroute had resolved that part

brycecWhy can't everyone just use Google?
they've got plenty of infrastructure
[15:31]
staticsafewut [15:33]
brycecAs a ping and traceroute destination.
v4 and v6 alike
[15:33]
mercutiogoogle don't stick location information in traceroutes [15:34]
brycecone name to remember... you're probably already typingit [15:34]
mercutiohave multiple data servers that traffic can randomly go to or through
like google seem to carry some traffic to the other side of the world :/
well sydney to amsterdam or something
also google do weird stuff, like show a ping of 24 msec, but load everything off a server 150 msec away
for things like their search
and google dns
like if you run a dns server, and look at logs, google can query from much further away addresses than 8.8.8.8
[15:34]
jlgaddisi would be very surprised if they originate queries from the ip addresses of their public dns servers [15:45]
mnathaniHere are the subnets from which Google Public DNS sends requests to authoritative nameservers, and their associated IATA airport codes:
64.233.162.0/24 gru
74.125.16.0/24 tpe
74.125.17.0/24 bru
74.125.18.16/29 ber
74.125.18.80/29 lpp
74.125.18.144/29 grq
74.125.18.208/29 grq
etc
all listed on https://developers.google.com/speed/public-dns/faq
[15:52]
mercutiojlgaddis: yeh but i mean it's not even the same country
for me i think it's taiwan or hong kong or something
[15:58]
.... (idle for 17mn)
jlgaddisit's going to depend on the physical location of the client that the original request came from
for example, a client in taiwan using 8.8.8.8 is going to hit google's dns server in taiwan and so they're going to be querying your authoritative servers from taiwan
if i look at the query logs on my authoritative servers, i see lookups from all over the place (as expected)
[16:15]
mercutioyeh
but new zealand isn't near taiwan :/
actually it's closer than los angeles
bizzare
ping is higher to there though
[16:17]
jlgaddisi guess i'm missing something... what does NZ have to do with anything? [16:19]
mercutioit's where i am
maybe some people are closer to the dns servers requests are made from
[16:19]
staticsafeNZ shall forever be the land of LOTR to me [16:19]
mercutioheh
anyway the point was that google isn't necessarily a good reference with tracerouting etc
cos their setup is more complicated, and sometimes hidden
[16:19]
staticsafealso anycasted yea [16:20]
mercutioand also doesn't have location information easily availble
like you can lokup where the google dns stuff comes from
but geoip database isn't accurate, and reverse lookups aren't obvious
or non-existant
[16:20]
jlgaddisheh, google uses the city tied to my ARIN POC record as the "location" for ip addresses allocated to us
even though i live a good distance away from where they're actually being used
(my personal address/po box is what's listed in my poc record, not the address of the company)
[16:22]
mercutiohmm all google addresses say california [16:27]
