Edits to `etc/resolv.conf` being overwritten

[Bone Baboon]

Any suggestion on how to stop my edits of `etc/resolv.conf` from being
overwritten?

`/etc/resolv.conf` is being overwritten removing changes I save to it.
My edits to `etc/resolv.conf` specify some name servers.  Some time
after my edits are saved the file is completely rewritten to it's
original contents before I made my edits.  The original contents include
nameserver, domain and search for my internet service provider's DNS. 

When I run `sudo herd status` it outputs:
