Accurate IP address verification
|
|
Expression |
((0|1[0-9]{0,2}|2[0-9]?|2[0-4][0-9]|25[0-5]|[3-9][0-9]?)\.){3}(0|1[0-9]{0,2}|2[0-9]?|2[0-4][0-9]|25[0-5]|[3-9][0-9]?)

Description |
Accurate IP address verification...
Each numeric part of an IP address must be between 0 and 255. All patterns I have seen on the net cover this range but they allow leading zeros. The valid cases are:
* 0
* 1, 10-19 and 100-199 aka 1[0-9]{0,2}
* 2 and 20-29 aka 2[0-9]?
* 200-249 aka 2[0-4][0-9]
* 250-255 aka 25[0-5]
* 3-9 and 30-99 aka [3-9][0-9]?

Canadian postal code format verification
|
|
Expression |
([ABCEGHJKLMNPRSTVXY][0-9][ABCEGHJKLMNPRSTVWXYZ])\ ?([0-9][ABCEGHJKLMNPRSTVWXYZ][0-9])
|
|
Description |
Accurate Canadian postal code format verification.
The format of a Canadian postal code is LDL DLD where L are alpha characters and D are numeric digits. But there are some exceptions. The letters D, F, I, O, Q and U never appear in a postal code because of their visual similarity to 0, E, 1, 0, 0, and V respectively. In addition to avoiding the six "forbidden" letters W and Z also do not appear as the first letter of a postal code (at least not at present).
