If you need to create regular expressions, there is no better regex editor for Mac than Expressions, with cheatsheets, syntax highlighting, and test mode at your fingertips. Find and replace text or numbers in Excel for Mac. You can search for text and, optionally, replace text. In your search terms, you can include special characters such as question marks, tildes, and asterisks, or numbers. You can search by rows and columns, search within comments or values, and search within worksheets or entire workbooks.

The standard (IEEE 802) format for printing MAC-48 addresses in human-friendly form is six groups of two hexadecimal digits, separated by hyphens - or colons :.

A little hard on the eyes, but this:

will enforce either all colons or all dashes for your MAC notation.

(A simpler regex approach might permit A1:B2-C3:D4-E5:F6, for example, which the above rejects.)

delimiter: ':','-','.'

double or single: 00 = 0, 0f = f

This regex matches pretty much every mac format including Cisco format such as 0102-0304-abcd

Example strings which it matches:

Mixed format will be matched also!

Be warned that the Unicode property p{xdigit} includes the FULLWIDTH versions. You might prefer p{ASCII_Hex_Digit} instead.

The answer to the question asked might be best answered — provided you have a certain venerable CPAN module installed — by typing:

I show the particular pattern it outputs here as lucky pattern number 13; there are many others.

This program:

generates this output:

Which seems the sort of thing you're looking for.

If you need spaces between numbers, like this variant

The regex changes to

RexSplodeRexSplode

to match both 48-bit EUI-48 and 64-bit EUI-64 MAC addresses:

where h is a character in [0-9a-fA-F]

or:

this allows '-' or ':' or no separator to be used

Maybe the shortest possible:

Update: A better way exists to validate MAC addresses in PHP which supports for both hyphen-styled and colon-styled MAC addresses. Use filter_var():

As I know, it supports MAC addresses in these forms (x: a hexadecimal number):

Thanks a lot to @Moshe for the great answer above. After doing some more research I would like to add my extra findings, both in regards to IEEE 802 and enforcing consistent separator usage in regex.

The standard (IEEE 802) format for printing MAC-48 addresses in human-friendly form is six groups of two hexadecimal digits, separated by hyphens -. It is however, widely adopted convention to also allow colon :, and three groups of four hexadecimal digits separated by periods ..

Full credit to @Moshe here for his initial statement, and to @pilcrow for pointing out that IEEE 802 only covers hypens.

Here is a regex that enforces that same separator is used throughout the mac address:

And here is an additional one that allows for use of no separator at all:

As a MAC address can be 6 or 20 bytes (infiniband, ...) the correct answer is:

you can replace : with [:-.]? if you want different separators or none.

Olivier LAHAYEOlivier LAHAYE

I don't think that the main RegEx is correct as it also classifies

as a valid MAC Address, even though it is not correct.The correct one would be:

So that every time you can choose ':' or '-' for the whole MAC address.

This one is a small one:

Have in mind, that weird mix of several chars or separators could pass.
