Wir arbeiten schon viele Jahre mit Hexonet und für uns gibt es nichts besseres oder vergleichbares. Hexonet bietet viele Vorteile. Erstens sind die Preise sehr gut. Zweitens ist das Dashboard sehr gut verständlich und einfach zu bedienen und drittens hat Hexonet einen absolut perfekten, schnellen und sehr kompetenten Support.

Der Domainchecker von Hexonet ist der schnellste Domainchecker den man überhaupt finden kann.
Einfach nur zu empfehlen!!!

This is the fastest domain checker I've seen. Very happy with this module and no longer worry about client downtime when making WHOIS checks.

The Hexonet support is superb. Just tell them what you want and they'll help in every way they can. Awesome!!
