REGEX for Multicast IP Address
asp.net, ip-address, multicast, regex
Solution
Personally I'd use math, but if you really want a regex,
^2(?:2[4-9]|3\d)(?:\.(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d?|0)){3}$
<---|------|--> <-----> <------> <---> <------> | |
| | | | | | | three more octets
| | | | | | |
| | | | | | 0
| | | | | |
| | | | | 1 - 99
| | | | |
| | | | 100 - 199
| | | |
| | | 200 - 249
| | |
| | 250 - 255
| |
| 230 - 239
|
224 - 229
Problem
I have gone through this wonderfull post on stackoverflow Validate IP address is not 0.0.0.0 or multicast address But this is a custom javascript function which i have to write in my aspx page, instead of this is there any regex equivalent which could be helpful to validate the multicast ip-address e.g. multicast IP address between 224.0.0.1 and 239.255.255.255 Thanks in advance for your efforts. :)
