I am writing a script that is supposed to switch IP address for specific FQDN and while I can mess with /etc/hosts directly I'd like to leave it vanilla and implement this some other way, preferably only for the user that executes the script.
Any suggestion?

It may be useful to know which OS you use.
I am not aware of any way to do this other than via the hosts file.
I have developed my own bash script to automatically update my hosts file from a popular source for the purpose of ad blocking etc.
It has been running with long host files for several years without any problems.
My script does this as root:
1 - copy routine content from original hosts file to a new file
2 - copy custom entries to new file
3 - filter/copy from published ad blocker site
4 - overwrite hosts file with new file
5 - flush DNS
It should not be too difficult to do this on a per user basis.
As long as you are happy to work as root don't be afraid of playing with hosts files but keep the original.

thanks for the answer! I am using macOS (I tagged it but didn't mention it in the post, apologies). I was going down that route as you described but would like to avoid running this as root. – user130888 – 2019-10-31T23:30:46.233

Sorry - missed tag. I mainly use OS X 10.6.8. My script is contained within a custom file at /Library/LaunchDaemons/hosts.plist which I load and edit via AppleScript. – Neville Hillyer – 2019-10-31T23:55:58.800
10.6.8? That's horribly ancient and unsupported. I only use it in a VM so I can run MT-Newswatcher. – Barmar – 2019-11-01T17:40:59.670
