Dlha odozva pri inicializacii spojenia

[Martin Tiršel]

DNS komunikacia je medzi danym serverom a ADSL routrom, nikoho dalsieho sa  
nepyta. Teraz som vypol IPv6 cez parameter jadra pri bootovani, ale stale  
skusa vytiahnut AAAA zaznam:

Existuje nejaka moznost, ako vypnut dotazovanie sa na IPv6 zaznamy?  
Instalovat a konfigurovat este DNS server, ktory na takuto poziadavku  
spravne zareaguje som v plane nemal :(
