I'm glad you got your domain results sorted out. I'v used BIND 8 and BIND 9 but not in several years. I use unbound because I don't need an authoritative (e.g. Internet facing) nameserver and its provisioning and management is simpler and easier for me.
In regards to your reserved address question, the low-order address of a subnet is for routing, the high-order address for broadcast.
Example with 10.1.1.0/24: 10.1.1.0 is for routing, 10.1.1.255 is for broadcast, so .1 through .254 are available for 254 devices.
Example with 10.1.1.0/29: 10.1.1.0 is for routing, 10.1.1.7 is for broadcast, so .1 through .6 are available for 6 devices.
Example with 10.1.1.8/29: 10.1.1.8 is for routing, 10.1.1.15 is for broadcast, so .9 through .14 are available for 6 devices.
Your /29 has a x.x.x.73 device, so I assume your subnet is x.x.x.72/29, where .72 is used for routing and .79 is used for broadcast.
(I've redacted your AT&T provided IP addresses, because that can be used for identification. You may want to edit your posts to redact the same information.)
