Ok it may sound strange, but I forgot where is one of my websites hosted.
I remember the domain name and I have access to setup the DNS server, but I don't remember the nameserver. It was something like ns113.icndns.net but I checked and the domain is not there. When I use that tool I see my domain name listed there: https://viewdns.info/reverseip/?host=nemo.icnhost.net&t=1 But what are the dns server names? Is there an easy way to find or am I missing something general knowledge? Please help.
p.s. I don'g have access to the hosting account and the guy having it will return at the end of the week, but it is too late.
