Rewrite Regex syntax -- Am I right?

[guillermo5000]

I have a rewrite that doesn't seem to work. Can anyone check my work. Thank you!

RewriteCond %{REMOTE_ADDR} ^00\.000\.6\.81$ [OR]
RewriteCond %{REMOTE_ADDR} ^00\.000\.6\.(7[4-5]¦8)$
RewriteRule .* - [F,L]

I'm attempting to catch
00.000.6.81
00.000.6.74
00.000.6.75
00.000.6.78

Perhaps the last rewrite should read

RewriteCond %{REMOTE_ADDR} ^00\.000\.6\.(7[4-5]¦78)$

?

Thanks all!

I'd suggest:

RewriteCond %{REMOTE_ADDR} ^00\.000\.6\.(7[458]¦81)$
RewriteRule .* - [F]

Replace the broken vertical pipe "¦" character with a solid pipe before use.

Ahh! Much simpler. Thank you!

For the sake of learning, does mine work?

Yes, it should work fine for the .74, .75, and .78 IP addresses. You have used a range "7[4-5]" and then a separate "78". When the range is only a difference of one (5-4=1), then the simpler "one of alternates" [45] method is faster, plus you can then add in the "8" making it 7[458], and then 'or' in the "81" as shown so that a second RewriteCond is not needed. "[4-58]" would also work, but again, since the range is only a difference of one, "[458]" is faster to process.

Thank you for the great info!
