Quoting Giampaolo Tomassoni <[EMAIL PROTECTED]>:
From: Jeff Chan [mailto:[EMAIL PROTECTED] There are lots of legitimate reasons to delegate zones, for example, migration to a new nameserver. I suggest you ask someone who runs major nameservers. I have.This is a temporary solution. Later you upgrade your registration records, right?
Sometimes it's temporary, sometimes it's not. Sometimes temporary solutions remain in place for many years. Delegation is a primary function of DNS.
