Bu tam bir cozumleme degil. ilgili domain icin sadece SOA kaydi var
ancak NS kaydi olmadigi icin cozumleyecek sunucular hangi
isim sunucusuna basvuracaklarini bilemiyorlar. Gercek bir cevapta
otorite kaydi olarak NS kayitlarinin verilmesi gerekiyor.
Ozet olarak aldiginiz bu cevap DNS cozumlemesi icin yeterli degil.
ns1.otenet.gr yoneticilerinin duzgun tanim yapmasi gerek.
