- Subject: [opennic-dns-operations] Should I act on bad notify attempts?
- Date: Sat, 09 Feb 2013 08:56:52 -0500
There are a handful of non-Master DNS servers that constantly try to notify my server. Should I act on this (block via iptables, etc.) or just accept that there will always be misconfigured servers somewhere and ignore them?
Thanks.
