Check If a String Contains IPv4 Address in VB.Net -


how can tell if string contains ipv4 address. want ip addresses in string.

exemple:

the following string contains 4 ipv4 addresses:

2016-01-16 00:00 - [99.245.14.88] downloaded ... 2016-01-16 00:00 - [120.103.139.95] downloaded ... 2016-01-15 23:59 - [166.118.4.233] downloaded ... 2016-01-15 23:59 - [55.234.129.191] downloaded ...

here code made each ip..

    dim regex new system.text.regularexpressions.regex("\[(([\d]{1,3}\.?){4})\]", system.text.regularexpressions.regexoptions.multiline)     dim matches system.text.regularexpressions.matchcollection = regex.matches(textbox1.text) 'replace textbox string source      dim tmp string = ""     each match system.text.regularexpressions.match in matches         'do each ip : match.groups(1).value         tmp &= match.groups(1).value & vbnewline     next      msgbox(tmp)

it uses regular expression, if going work text lot should read how work. if looking don't forget mark answer , upvote.
