When passing in a comma separated list of ranges, I'm continually met with Invalid IP address, regardless of format. Because I have to add one CIDR range at a time, the result is adding a handful of rules rather than a single rule with multiple ranges.
From the docs for az webapp config access-restriction add
--ip-address
IP address or CIDR range (optional comma separated list of up to 8 ranges).
My attempts:--ip-address 52.151.220.252/32,52.151.221.14/32--ip-address "52.151.220.252/32","52.151.221.14/32"--ip-address "52.151.220.252/32,52.151.221.14/32"
