I'm trying to edit [an answer](https://superuser.com/questions/86617/2wire-modem-to-linksys-router/354223#354223) I wrote a while back to correct an important item.

When I select "Save Edits", it gives me an error with the following:  
"Oops! Your edit couldn't be submitted because:

    Your post contains a link to the invalid host '192.168.1.254'.
    Please correct it by specifying a non numeric domain or wrapping it in a code block."

What in the world is it asking for?  What the heck is a "code block"?

The original question and answers deal with how to set up a router and there will always be multiple references to private IPs like 192.168.x.x and 10.x.x.x.
It didn't complain when I originally posted.  Why does it complain now?

Any article dealing with network devices will need to contain private IPs.
How do I turn off this type of "error" checking so I can correct the original answer?

Why are you making it so hard when I'm just trying to help by answering someone's question?
Now I have to post my own question about this nonsense and wait for an answer before I can finish the correction.

Please tell me how to disable this "error" checking.

Thanks
