The documentation is missing the DNS Operator chapter. Possibly this is due to a relocation/refactor in the documentation, which moved from the following:

- `html/networking/dns-operator`

to the following:

- `html/networking_operators/dns-operator`

It seems only 4.16 version is impacted. Please double check.

4.16

Compare 4.15 [0] and 4.17 [1] URL location for the DNS operator chapter, and then check that the same format for 4.16 doesn't work in either the URLs [2] [3] (HTTP 404)

    1. Open 4.15 docs [0]
    2. Select 4.16 version
    3. Observe it's not redirecting to anything
    4. Try to manually tweak URL values for 4.16
    5. HTTP 404
    

HTTP 404
