If you are looking for DNS to support a domain name, the authority for that comes from the owner of the domain name (not ampr.org <http://ampr.org/>). If you are trying to provide reverse lookups for your 44.x IP addresses, that authority is provided by the owner of the parent address block (ardc.net) It can work, if you know what you are doing. But delegation of your 44.x address block is not provided by default. You can request delegation of your IP address space from Chris. He will delegate your specific address(es) to your specified nameservers. You need at least two separate machines, preferably at two different physical locations. The IP addresses of your namservers must be very stable. If you have never done it before, setting up DNS properly is far more complex than getting your BGP routing to work. It is also far beyond the scope of something that can be handled on this mailing list. I would suggest a web search for “how to setup DNS nameserver.” It may be helpful if you include your OS of choice, such as “Debian Linux" or "FreeBSD." — Dave K9DC, K9IP
