RewriteCond

.htaccess

[xt35]

I need to block the range #*$!.xxx.0.0 - xxx.xxx.112.255

Please show me the RewriteCond for that range.

Thank you.

Bump

It seems my simple question was bypassed :(

Please, let me know how to block the range ***.***.0.0 - ***.***.112.255. How must be the RewriteCond written for that?

Thanks

ok :)

Here is what I'm using now

RewriteCond %{REMOTE_ADDR} ^(***.***.[0-112].*)$ [OR]

Is it correct?

[jdMorgan]

No. The reason is that regular expressions work on characters, and there is no "meaning" or "value" associated with them -- they are just characters. Regular expressions does accept character ranges, such as [a-z] and [3-7], but again, these are regex character ranges, and not scalar ranges.

In order to match a numeric range of 0-112, you have to cover all possible character combinations:

[0-9] for 0-9
[1-9][0-9] for 10-99
10[0-9] for 100-109
11[012] for 110-112

So the whole mess, when put together, looks like this:

^***\.***\.([0-9]¦[1-9][0-9]¦10[0-9]¦11[012])\.

You can shorten that slightly, to:

^***\.***\.([1-9]?[0-9]¦10[0-9]¦11[012])\.

(You can ignore the final 0-255 octet of the IP address, since all values are to be matched (accepted).

Replace the broken pipe "¦" characters with solid pipe characters before use; Posting on this forum modifies that character.

Jim, thank you very much for the explanation, now I think I understand a bit how should the ranges be written :)

I need a confirmation if the below samples are correct:

1.
to block from ***.***.0.0 - ***.***.63.255 the condition looks like ^***\.***\.([0-9]¦[1-6][0-3])\.

2.
to block from ***.160.0.0 - ***.162.255.255 the condition looks like ^***\.16[0-2]\.

Thanks again.

[jdMorgan]

That looks correct to me.
