Regex for BGP 32Bit Private AS Range

[neilobrien]

Hi All,

Similar to the regex /(6451[2-9]|645[2-9][0-9]|64[6-9][0-9][0-9]|65[0-4][0-9][0-9]|655[0-2][0-9]|6553[0-5])/ for 16bit Private AS 64512-65535, I'm looking for a regex that will cover the 32bit Private AS Range 4200000000 - 4294967294.

Unfortunately, /[4200000000-4294967294]/ won't work in my case, I could use /42[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]/ but I think that casts the net too far.  

I've been looking around and can't find anything suitable.

Thanks in advance,

Neil

The last expression seems the one to work. It can't cast the network too far as 4294967294 is the limit.

HTH.
