Using the 0-255 regex of last post you can build a more complex regex. Because I never worked with IP addresses I consulted Wikipedia to understand ranges IPv4, private network addresses <https://en.wikipedia.org/wiki/Private_network#Private_IPv4_addresses>. *IPv4, private network: 192.168.0.0 – 192.168.255.255* *(\b192\.168(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\b){2})* I'll explain this one. The others should then be readable. *( *= open capture group 1 *\b *= word boundary 198 literal *\. *= escape for literal stop-mark (otherwise *"."* matches any character) 168 literal *( *= open capture group 2 *\. *= literal stop-mark *( *= open capture group 3 *[0-9] etc.* = regex we made in last post to match 0-255 *) *= close capture group 3 *\b *= word boundary *) *= close capture group 2 *{2}* = repeat pattern in group 2 twice *) *= close capture group 1 *IPv4, private network: 10.0.0.0 – 10.255.255.255* *(\b10(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\b){3})* Much like previous, notice *{3}.* *IPv4, private network: 172.16.0.0 – 172.31.255.255* *(\b172\.(1[6-9]|2[0-9]|3[01])(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\b){2})* This is a bit more complex as it needs 2 ranges. *16-31* and *0-255*. N otice *{3}.* *IPv4 private networks starting: 10, 192.168, 172.16* *(\b(192\.168|10|172\.(1[6-9]|2[0-9]|3[01]))(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\b){2,3})* This combines the three above into one regex. More advanced, but gives idea you can combine things. Notice* {2,3}.* Test for this more complex one *-> ... is match* _Should NOT match_↩︎ 9.255.255.255↩︎ 10.0.0.00↩︎ 147.168.255.255↩︎ 172.32.255.255↩︎ 172.14.255.255↩︎ 192.168.1.256↩︎ 192.27.255.255↩︎ ↩︎ _Should match_↩︎ ->10.0.0.0↩︎ ->172.16.89.125↩︎ ->192.168.1.1↩︎ ->192.168.1.255↩︎ TT -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
