Maximum number of IPs in a NSG rule

Question

What is the limit for the number if IP addresses that can be set as destination IP per NSG rule?

For example, if I needed to allow 100+ IPs in an outbound NSG rule, is there a limit that preventing me adding multiple IPs?

Thanks.

Hello sdon,

You can only add up to 4,000 Source IPs. To save on space (and if possible), I'd suggest you use CIDR notation (for a range).

You should be good to use 100+ IPs in an outbound NSG rule.
