When I use those directly, there is no rotating. When I go to the modem with either windows or FreeBSD then I get rotation. I don't see where else the rotation could be occurring. > > -- Doug I'm not sure I correctly understand your problem but it sounds like you are expecting deterministic behavior that you will not be able to get due to the nature of how DNS works. There are a lot of factors that come into play. If you do a web search on DNS with multiple A records there is a lot of discussion about it. Although this article is about round robin it also discusses the different issues with having multiple A records. https://en.wikipedia.org/wiki/Round-robin_DNS - John J.
