NimbostratusSimple Question regarding Address type Data Group List
Guys, I have a question regarding Address type Data Group List.
If in my data group list I add this host 0.0.0.0, will it match all IP's?
Also is there a way to add comments in Data Group Lists? For documentation sake.

Hi Anujl,
0.0.0.0/0 will match any IP. And no, you can't add comments to a datagroup. You could open a case with F5 Support to request this functionality.

anujl_5566Thanks Aaron,
Just to confirm, you wrote 0.0.0.0/0? BUT if I add a host 0.0.0.0, it will be 0.0.0.0/32. So should I add a network 0.0.0.0, with mask 0.0.0.0?
