Hi Darren, Thank you for the quick response and clarifications! I see the stable version for option-class-tagging will be 3.0.0 per previous mail, how about the ‘client-classes’ feature? Will it be the same?

I'll try to clarify theses. - option-class-tagging (https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fkea.readthedocs.io%2Fen%2Fkea-2.7.5%2Farm%2Fclassify.html%23option-class-tagging&data=05%7C02%7Cyu.xiao%40cox.com%7C13f3cc3e7ef34889359508dd34aba747%7C9feebc97ff0442c9a152767073872118%7C1%7C0%7C638724634039859910%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=HO0Ms2q8RsYqsewLVZpP3NYqa2kt3AoubgvLgdnBHII%3D&reserved=0<https://kea.readthedocs.io/en/kea-2.7.5/arm/classify.html#option-class-tagging>) - This is a completely new feature that allows the use of a class guard ("client-classes": [ <list> ]) inside of an option. This limits the option availability to only those clients that are members of one of the classes in the list. - client-class -> client-classes - the former "client-class" is now "client-classes" and is a list. This allows you, for example, to allow members of more than one class to obtain an address from a pool. No longer will you have to make meta-classes testing membership in several other classes. For an example of this change, see: https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fkea.readthedocs.io%2Fen%2Fkea-2.7.5%2Farm%2Fdhcp4-srv.html%23reserving-client-classes-in-dhcpv4&data=05%7C02%7Cyu.xiao%40cox.com%7C13f3cc3e7ef34889359508dd34aba747%7C9feebc97ff0442c9a152767073872118%7C1%7C0%7C638724634039884540%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=NTMvbu67AOdxcWF5BzW3XyYK1ZHoGxPQQzvfYPlGO70%3D&reserved=0<https://kea.readthedocs.io/en/kea-2.7.5/arm/dhcp4-srv.html#reserving-client-classes-in-dhcpv4> - require-client-classes -> evaluate-additional-classes - This change is merely a renaming to make it more clear what the functionality actually does. The naming was unclear before and led to confusion (see: https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fkea.readthedocs.io%2Fen%2Fkea-2.7.5%2Farm%2Fdhcp4-srv.html%23additional-classification&data=05%7C02%7Cyu.xiao%40cox.com%7C13f3cc3e7ef34889359508dd34aba747%7C9feebc97ff0442c9a152767073872118%7C1%7C0%7C638724634039901005%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=QAgXJHRPOtB3S6mqUZHHhJQPgrwIKxo31ZQLSf04nQM%3D&reserved=0)<https://kea.readthedocs.io/en/kea-2.7.5/arm/dhcp4-srv.html#additional-classification> Thank you, Darren Ankney On Mon, Jan 13, 2025 at 3:00 PM Xiao, Yu (CCI-Atlanta) via Kea-users <kea-users@lists.isc.org> wrote: > > Hi ISC team, > > > > Last year, during my testing, I found that we can configure one client class > string to a subnet definition, but the configurations won’t be changed.
