We have delegated (most of) our reverse zones to: <a href="http://ns.nextra.sk" target="_blank">ns.nextra.sk</a> <a href="http://ns1.nextra.sk" target="_blank">ns1.nextra.sk</a> <a href="http://dns.nextra.sk" target="_blank">dns.nextra.sk</a> <a href="http://dns.gtsi.sk" target="_blank">dns.gtsi.sk</a> Some time ago, since there were some problems, I removed the <a href="http://dns.nextra.sk" target="_blank">dns.nextra.sk</a> record from the <a href="http://nextra.sk" target="_blank">nextra.sk</a> zone, and assigned its IP address to <a href="http://ns.nextra.sk" target="_blank">ns.nextra.sk</a>. No direct zones were delegated to it (hopefully, not by us), this caused no problem there (at least not caused by us). However the delegations in RIPE do still point to <a href="http://dns.nextra.sk" target="_blank">dns.nextra.sk</a>. There are plenty of them, and I plan to change the NS scheme to make it more reliable, easier to implement and harder to abuse (e.g. naming only some of NS records), so the structure will change even more. For this reason I decided not to change all delegations (to spare our RIPE contacts from modifying it all twice) until I will do that. However on Feb 24, RIPE sent lameness notifications to us and our RIPE contact got angry at me for not notifying them about this change, and requesting that I add the record back. I prefer not to do that, since my plans are very different and customers tend to put anything to NS records without asking. Adding CNAME record would not solve this problem since NS must not point to CNAME (scripts at RIPE check for that, right?). So I'm asking you for an advice - is it possible to mass-remove the "<a href="http://dns.nextra.sk" target="_blank">dns.nextra.sk</a>" from delegations?</blockquote><div> Write an script to mass change all your delegations and send it all as GPG/PGP signed mail. </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> - would it cause big problem if I kept it as it is, even if <a href="http://dns.nextra.sk" target="_blank">dns.nextra.sk</a> does not exist?
