I've been using DreamHost for my domain registrations for years and run my own DNS server. Through the control panel I used to update the dns nameservers for my domains, which involved going to the Registrations page, Modifying WHOIS, and entering the new nameserver name. After entering a name, if it was unknown, I'd be prompted for the IP of that nameserver, as necessary to complete the glue record.
I last changed these a few months back. Recently, it appears the Modify WHOIS portion of the panel page has changed, and now there is a dropdown where I can select "nameservers" and then select "use another hosts nameservers", and then enter the name(s) of the other DNS servers. However after I do this, I am no longer prompted for the IP(s). I get a success message, but without the IP, I know the glue record is invalid (and updates don't seem to be occuring to the root dns servers). I've tried entering just the IP on that page, but that isn't working either.
Anyone familiar with this? Thanks in advance.
