Just wondering if any1 here uses any DNS software on their systems which I might be able to use and or adapt to serve some uControllers which will only ever require 2 addresses and have inbuilt localized independent address for specific DNS service?
Both servers for these uC's while housed physically side by side in a specific business premises will be using different ISP's for internet access
Primary address 1 will always be to a fixed IP address.
Secondary address 2 will be on a dynamic address.
The DNS service for these servers will be via a 3rd fixed IP address which will be publicly unlisted.
( I would also prefer to get both server address off the public DNS listings if possible also by using this privatized DNS service. )
The main idea here is to get a little bit of redundancy in the event of attack on the servers for these uC's in order to keep the communications open. (There could be several thousand uC's connected at any given time using a simple keep alive similar to the messaging used in VoIp systems. Notification alarms are raised at the servers if the uC's fail to keep alive over certain time periods)
I will need to be able to have the main servers communicate any server address changes to this localized DNS service immediately in order to get fast propagation whenever there is a change of IP address.

Re: DNS software
I don't know if this is along the lines of what you need but.
I run Treewalk DNS on my PC, effectively becoming my own DNS server.

Re: DNS software
Thanks Zach, I will take a look at it and compare with others for sure. I have briefly been looking at http://www.maradns.org/ which seems quite good & I think may even be able to be run direct of some modem / routers which would suit very nicely if I can get communications between the uC servers & this DNS service happening locally.
any1 else s suggestions welcome.

Re: DNS software
Thanks Lucifer. As to why I ask this question, quite simply I have never had reason to look much at DNS before as generally speaking in most cases this is taken care of by the ISP or on some of the more corporate networks I have looked at it is taken care of by the people in charge of their infrastructure meaning DNS has never been an issue for me to worry about.
In this case, this infrastructure has been set up by a guy who is supposedly the Australian distributor for these uC's & has now seemingly disappeared without trace & has left some quite serious flaws in the way he has set this all up in the 1st place in this monitoring center.
1 of these flaws as I see it is the lack of a monitoring center supplied DNS service when the uC's are actually requesting this as part of their connection parameters. ( This request is completely separate from & not linked to any DHCP allocation by the local router at the client uC end.)
( I also have contacted the manufacturer of these uC's who initially tried putting me in touch with the guy who is supposed to be the Australian distributor & who has disappeared, followed by another guy who is a software developer who knows the units a little but has not had a great deal to do with them. His knowledge has gotten me to a point where I now have enough knowledge to get them running, but by no means stable which seems mostly related to scratchy lookup with these uC's.)
It is a pity to see this as the basic concept behind this is quite a good idea & I would like to see it developed to it's true potential, so I am willing to see what I can do to get this system working smoothly.

Re: DNS software
Hi,
I remember someone posted about a year ago a link to a real good dns tool in Off Topic.
It was good for bypassing your ISP and faster dns resolving. Unfortunately I can't
remember anymore the name and also can't find it anymore with the search.
If anyone of you know what I mean I would appreciate to know about it.
At this moment I'm using Acrylic dns doing also a good job.

There is a difference between knowing the code and writing the code.
May the code be strong in your projects.

Re: DNS software
You're probably thinking of Treewalk DNS, that I mentioned above.
It's been a go-to for years, for people bypassing their ISP DNS servers.

Hi,
Can't remember if that was the one, but anyway the site to download treewalk, http://treewalkdns.com/
seems to be dead.

Re: DNS software
I was at the site not too long ago, its probably just having issues with a server or something.
If it were truly dead, you would not see a 500 error code. That is a fatal error on the server itself, due to a messed up setting or some such, which is preventing it from working properly.
I'm sure it'll be back eventually.
Here is a site explaining how Treewalk works, note: TWDNS used to be called BIND-PE
