'Can't reach server' on all the servers except EU1 and EU2

[TheStrycker]

So i wanted to join some servers and it wouldn't let me because it was something with the host or whatever.
I went to google and found some help on the forum, did the DNS stuff and in the comments it said: 'i've found a way to fix this problem, change for example eu1.mcsg.in to 1.eu.mcsgn.in' this actually worked for eu1 and eu2 but not for the rest.
With the other server I get 'Can't reacht server'..
Can someone help me out?
Thanks.

im having the same problem dude, it says "cant resolve host name" and i typed the name in right, part of it is im not sure if its 1.5.1 or just 1.5. but still ive tried both .jar files and i get the same thing, i also tried the DNS stuff and no luck...

Make sure it is typed correct.
Also I think you meant "can't reach server" not

'Can't reacht server'
.
