What in the world is a "code block"?

Question

I'm trying to edit an answer 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

Answer 1

A code block is what you used to quote the error message above.

I am a code block. My text contents are printed *verbatim* in a typewriter font.
New lines are printed just like in the source text.
To create me, indent every like with 4 leading spaces, or select some text and
click the button labeled "{}"

I am a quote. I support highlighting and use a regular font. Simple line breaks are ignored just like in regular text. To create me, select some text and click the button labeled with a quotation mark.

The offending part of your answer on the main site is this:

You get to the hard core 2Wire 1800HG/2701HG Gateway configuration pages by using this URL: (url I cannot post for obvious reasons)

Just wrap the URL in backticks (used for inlining code in regular text), like this: http://192.168.1.254/mdc.

Answer 2

It appears to be trying to parse the IP address into a hyperlink and suggesting you should put it in a code block to stop it trying to parse the invalid address.

You can do code blocks by highlighting your text and clicking the {} button or pushing "CTRL+K"

A single line indent with text between two of these grave accent character is the single line version `

A code block is similar to a quote except it has formatting for code readability, it also prevents tags from being parsed so the code can be viewed instead of the affect, it's used a lot more on stacks like StackOverflow than SuperUser.
