Using a list as input to a function

I have a function that translates subnet IPs into IP ranges, but I need to input a list of subnets to this function and I am having trouble doing it:

My function at the moment:

import ipaddress


cidr = ["187.11.62.93,187.11.62.95"]
def get_ip_range(cidr):
    net = ipaddress.ip_network(cidr)
    return net[0], net[-1]

I also need the output in JSON but at the moment that is not a worry for me.

return[net[0],net[-1] for net[0],net[-1] in cidr]

I should have 2 IPs here, the lower and the upper IP of the range, but I am failing.
