A little hard on the eyes, but this:

<pre><code>/^(?:[[:xdigit:]]{2}([-:]))(?:[[:xdigit:]]{2}\1){4}[[:xdigit:]]{2}$/

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

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

Be warned that the Unicode property <code>\p{xdigit}</code> includes the FULLWIDTH versions. You might prefer <code>\p{ASCII_Hex_Digit}</code> instead.

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

<pre><code>% perl -MRegexp::Common -lE 'say $RE{net}{MAC}'
</code></pre>

I show the particular pattern it outputs <a href="https://stackoverflow.com/questions/4246077/simple-problem-with-regular-expression-only-digits-and-commas/4247184#4247184">here</a> as lucky pattern number 13; there are many others.

This program:

<pre><code>#!/usr/bin/env perl
use 5.010;

use warnings qw&lt;FATAL all&gt;;

my $mac_rx = qr{

The correct one would be:

<pre><code>((([a-zA-z0-9]{2}[-:]){5}([a-zA-z0-9]{2}))|(([a-zA-z0-9]{2}:){5}([a-zA-z0-9]{2})))

blocks|key|868731|text|因为MAC地址可以是6个或20个字节(infiniband，...)正确答案是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|868732|%5E([0-9A-Fa-f]{2}:){5}(([0-9A-Fa-f]{2}:){14})?([0-9A-Fa-f]{2})$|code-block|syntax|javascript|868733|您可以将:替换为:-.？如果您想要不同的分隔符或不需要分隔符。|868734|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

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

<pre><code>^([0-9A-Fa-f]{2}:){5}(([0-9A-Fa-f]{2}:){14})?([0-9A-Fa-f]{2})$
</code></pre>

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

blocks|key|1083753|text|这可以用在我的MAC地址的测试中，这个解决方案只适用于理想的MAC地址，如下所示。XX:XX:XX:XX:XX:XX|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1083754|(([a-fA-F0-9]{2}[:]){5}[a-fA-F0-9]{2})|code-block|syntax|javascript|1083755|entityMap^0|15|H|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

This could be used tested in sublime with my MAC address
This solution will only work with ideal MAC address That will look like this.. <code>XX:XX:XX:XX:XX:XX</code>
<pre><code>(([a-fA-F0-9]{2}[:]){5}[a-fA-F0-9]{2})
</code></pre>

blocks|key|868856|text|这是一个小的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|868857|(([0-9A-F]{2}[:-]?){6})|code-block|syntax|javascript|868858|记住，几个字符或分隔符的奇怪组合是可以通过的。|868859|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

This one is a small one:

<pre><code>(([0-9A-F]{2}[:-]?){6})
</code></pre>

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

blocks|key|1083082|text|最好的答案是mac地址验证正则表达式。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1083083|%5E([0-9a-fA-F][0-9a-fA-F]:){5}([0-9a-fA-F][0-9a-fA-F])$|code-block|syntax|javascript|1083084|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

the best answer is for mac address validation regex

<pre><code>^([0-9a-fA-F][0-9a-fA-F]:){5}([0-9a-fA-F][0-9a-fA-F])$
</code></pre>

In this format:

<pre><code>3D:F2:C9:A6:B3:4F
</code></pre>

or:

<pre><code>3D-F2-C9-A6-B3-4F
</code></pre>

What is a regular expression for a MAC Address?

Perl

格式如下：3D:F2:C9:A6:B3:4F或者：3D-F2-C9-A6-B3-4F
