Instead of BIND9 we are thinking about to<br /> use PowerDNS because of some really nice features (e.g.database <br /> backend,<br /> web based administration, fast,secure ...)<br /> <br /> Now we figured out that the DDNS(RFC 2136) is some kind of<br /> 'experimental' in PowerDNS. Before we do a PoC we want to ask if there<br /> is any experience or best practice
using PowerDNS as internal DNS for<br /> mid-size or large companies instead of BIND9? Especially some<br /> information woukld be good if DDNS with ISC DHCP works like a charm.<br /> Additional we want to do a split-horizon setup and PowerDNS does not<br /> have 'views' like BIND. The question is now how to solve this<br /> (additional PowerDNS instances?). We have also read pro and contra <br /> about<br /> the idea to use mysql replication (we plan to do a 'hidden primary'). <br /> Is<br /> mysql replication still recommended instead of zone transfer?<br /></blockquote> <br /> If you do DNS zone transfers between the master and the slaves, you do<br /> need some out-of-band provisioning for your slaves, e.g. if a zone is<br /> added or removed, the slave needs to know about it. For adding zones <br /> you<br /> could use the supermaster feature (but NOTIFYs may be missed sometimes<br /> and then your slave is not provisioned), but there is no solution for<br /> deleting zones.<br
/> <br /> If you use database based replication, then there is no need to care<br /> about this things.<br /> <br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #ad7fa8; padding-left: 1ex;"> We have<br /> around 700 clients which are using DDNS (ISC DHCP) and ~1500 server<br /> (fixed ip of course) located in different datacenter. Not too much but<br /> still growing...<br /></blockquote> <br /> Did you say that you want database replication between 1500 servers?<br /></blockquote><br />Sorry, it was a very bad description: We have around 700 client <br />workstations/laptops which are served by dhcp to get a ip address and <br />~1500 server which have static ip. The client address/hostnames need <br />also to be available by DNS. Therefore we use DDNS for the clients. The <br />clients are spread in three different offices and the server also spread <br />over different datacenter. The main architecture we currently thinking <br />about
are based on traditional concepts/architecture (e.g. hidden <br />primary, split-horizon,...).<br /><br />Meanwhile we are testing PowerDNS. It seems not suitable for us because <br />of different problems which we figured out with DDNS and the resolver <br />:-( We still keep an eye on PDNS and maybe in the future we give PDNS a <br />try but at the moment it is not ready for production in our environment <br />(with our special needs)...<br /><br />kind regards,<br />Marco<br /><br /><br /><br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> regards<br /> Klaus<br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #ad7fa8; padding-left: 1ex;"> <br /> The big question:<br /> Is PowerDNS a complete solution for a internal DNS infrastructure, do <br /> we<br /> have to think about a mixed environment (PowerDNS/BIND) or should we<br /> still use bind in the future?
