I think in use views with diferent zones files, all for same domain, no recursive querys, one view for each network/AS that my bgp router know. <br><br><div class="gmail_quote">On Thu, Aug 25, 2011 at 6:36 AM, Matus UHLAR - fantomas <span dir="ltr"><<a href="mailto:uhlar@fantomas.sk">uhlar@fantomas.sk</a>></span> wrote:<br>

I like to know if bind 9.8 have a limit of view?<div class="im"><br>
There is any number or I can create something like 1 million views<br>
without problems?<br>
There is any performance implication in use to many views?<br>

I use about 120 views. It accure 1,8gb of RAM in Idle. You must limit recursive cache to 32-64MB per view, and forward all recursive queries to another DNS server (I use powerdns-recurser at 127.0.0.2) for best perfomance.<br>

you can also use attach-cache directive to share a cache betwween multiple views. If your views only differ by loaded zones, that should not be a problem.<br>
<br>
If it's not possible, you (or the OP) can surely configure 120 or e.g. million real or virtual machines to provide the DNS service. That is just what views do within one BIND process.<br><font color="#888888">
