title: Hosting DNS to allow reverse lookup
body: <p>I've only recently begun scratching the surface of hosting my own DNS, but I'm looking to do so in the hopes that I can facilitate my own reverse lookups.</p>
  
  <p>My idea being that if I can manage my own DNS, I can give it tables I've complied about IP / FQDN relations so I can do a reverse lookups on dynamic ips (of which I know the FQDN of) without my ISP's support; I'd pair the return of something like an nslookup somewhere within my own hosted DNS then have that DNS server facilitate reverse DNS lookups for some programs that require the function (like for a CFEngine Hub)
  Near as I can tell, the 'PRT' record is what I want to spoof; <a href="https://www.siteground.com/kb/what_is_a_ptr_record_and_how_to_add_one/" rel="nofollow noreferrer">Right?</a></p>
  
  <p>I'm wondering if there are better resources out in the wild to use. <a href="https://askubuntu.com/questions/245707/not-able-to-get-the-reverse-dns-working">This</a> and <a href="http://www.itworld.com/article/2833006/networking/how-to-setup-reverse-dns-and-ptr-records.html" rel="nofollow noreferrer">this</a> are the best I've found about hosting DNS in this manner.</p>
  
  <p>Any pitfalls I'm not seeing about trying to pursue this convoluted solution? </p>
