<div dir="ltr">1) It's up to you, if your zones are small and keys are long, you can live without rotation longer. For example we rotate KSK every year and ZSK every 3 months with SHA256 and 10M records in zone. Also take a look at <a href="http://tools.ietf.org/html/rfc6781">http://tools.ietf.org/html/rfc6781</a> <br>
<br>2) Child zone doesn't need to be signed with the same key(s) as parent.<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/10/31 staticsafe <span dir="ltr"><<a href="mailto:me@staticsafe.ca" target="_blank">me@staticsafe.ca</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I have recently started signing all of my domains that I possibly can. I have a couple of questions.<br>
<br>
1) Are there any recommendations on how often keys should be rotated? Best practices to perform during the rotation process?<br>
<br>
2) I have a zone <a href="http://ircops.org" target="_blank">ircops.org</a> delegated to my own NSes, in it there is a sub-zone <a href="http://dnsbl.ircops.org" target="_blank">dnsbl.ircops.org</a> delegated to other nameservers. Does <a href="http://dnsbl.ircops.org" target="_blank">dnsbl.ircops.org</a> need to be signed with the same key(s) as <a href="http://ircops.org" target="_blank">ircops.org</a>?<br>
