a kontroloval jsi, zda z toho stroje jde skutecne zjistit IP toho 
WWWcka?

podle korenovych DNS pro CZ by mel DNS pro servis24.cz byt
servis24.cz.            18000   IN      NS      nsb.csas.cz.
servis24.cz.            18000   IN      NS      nsd.csas.cz.

nsb.csas.cz.            18000   IN      A       193.179.187.18
nsd.csas.cz.            18000   IN      A       62.40.76.18

ale nas DNS server kesuje:
www.servis24.cz.        554     IN      NS      css1.csas.cz.
www.servis24.cz.        554     IN      NS      css2.csas.cz.

;; ADDITIONAL SECTION:
css1.csas.cz.           6891    IN      A       194.50.240.64
css2.csas.cz.           6877    IN      A       194.50.240.192

cili zrejme uplne jine stroje. Pravdepodobne doslo ke zmene v 
nastaveni zony a jsme prave uprostred prechodu na nove DNS...

jak stare tak nove DNS mi vraceji IP pro www.servis24.cz (ale objevuji 
se 2 ruzna IP). DNS cssx znaji www.servis24.cz ale domenu servis24.cz 
hlasi jako neexistujici

Nove servery pri dotazu na SOA,NS vraci misto pocekavane odpovedi jen

;; QUESTION SECTION:
;servis24.cz.                   IN      NS

;; ANSWER SECTION:
