I find it both amazing and concerning that there are people who claim to be either an ISP or an SP and don't understand DNS.
The solutions suggested are 10 minute jobs at most and should be valid for the lifetime of your environment. There should be no need to touch it 5 times a day.
Using bind; Zonefile 333.222.111.in-addr.arpa $GENERATE 1-254 $ PTR 111-222-333-$.dns.isnt.scary.com
Rinse and repeat for every ip netblock you are authoritative for.
When you get serious about fixing your dns, you can start populating that zonefile with real entries in parallel.
But if you are struggling with adding the /etc/hosts entries via a script, then I fear bind is probably too advanced for you...

Joseph,
The customer premisses equipment (CPE) are managed and accessed internally for monitoring and maintenance of customer internet connection. Customers are not eternal.
Can you imagine to a system administrator expends all the day adding hostnames in a DNS Server for at least 10 CPE per day that can be changed 2 days after or a weekend after? Or even adding hostnames in the /etc/hosts for five devices that will be removed after 6 hours?
We have system that only needs a screw to be adjusted, and people with the screwdriver in the hand. Are you asking me to search for a screwdriver and reach the screw to be adjusted?
All the service providers I know, does not control CPE units with hostnames. They use hostnames for servers, main routers, main switches, and other devices that are usually in the Data Center.

It is one time, unless your organization's public IP allocations are regularly changing.... (I am asusming, of course, that you would take care of all your RFC 1918 subnets at one time, but if more come into use, you could add still add them without any effort at all)
If these "CPE" devices are using a public IP address that your organization doesn't control, then yes, you would have to add
internal
hosts entries for any such IP(s) that you care about.
But again, a script can do this in a split second, and could easily
be
written to take a CIDR-syntaxed subnet argument...
This sort of "limitation" should never halt an ISP in its tracks. I mean, Observium is open source.... there is nothing stopping you from patching it directly to do what you want, and maintaining said patch,
so
if that scenario fits your use case (temporarily monitoring equipment living on public IPs of other organizations), then it sure would make sense to customize your Observium setup to work with it, if
maintaining
a DNS server or hosts file is too much work for you.

Can you think on this scenario?
Who uses the information, and who uses the system?
Is it necessary to be an system administrator or a network
Engineering
to uses the system? Or my Help Desk team will be able to add an CPE for monitoring too?
You are developing a system for big ISP and big companys, but
thinking
small.
