so ive been reading a little about dns and what they do and how graphs around the place say of reaction times,

with the argument that there is no need to change from the standard isp in most cases, my question is does the xnet dns support anycast, cause when i use xnet dns to watch youtube videos the transfer everytime i remembered to look at it came from v2.lscache8.c.youtube.com, which was showen as listed in the middle of the us.on different videos.

the xnet dns ip or the contractor it pays to maintain its list always pick that route for traffic? because that what its listing says if im making sense? who does maintain this for the isps, webcrawlers?  Akamai vs google nz,

 after changing to google dns, it changes almost every time on different videos also of course, quite abit a orcon.alk.cache, which never came up be for,

so after the inital reaction time of the dns look up, should provide a quicker load time due to effectivly speading the load better through better logic ie anycast and programming(which google has been ok at so far),its bring the local orcon cache into my world, when i couldnt see it b4, i dont seem to be getting no love from xnet cache,  that i can see.\

google has tons of search listings and ip address from nz to use to start with, how much data usage info about nz would a company like Akamai have about a litte country like us?

the dns just says ok go look at this address none of the page info passes thorugh the server that lists the dns,

AND if i use telecoms or slingshots dns will that let me in on there caching?

the google dns found its way into data that was stored on orcon that was revelant and local to me, google always uses your ip adress in the math to bring you listings that are related to your country in serches so i guess they would do the same in dns.

ive gone on long enough, any thoughts that relate to what im getting at, and a solid answer from some one in the know about the telecom or slingshot dns caches would be good
