python 3.x - Python3 For loop - not looping?

Question

I'm assuming I'm doing something silly but why is my loop not looping? in the end the only thing that gets saved to my dict is the latst CIDR:IPs

blocks = ['12.2.0.0/28', '13.8.0.0/28']
n + 1

#setup dictionary and lists to store cidr and ips
data = []
ipdict = {}
breakpoint()
for x in range(len(blocks[:])):
    print(blocks[x])
for cidr in ipaddress.IPv4Network(blocks[x]):
    data.append(cidr)
    print(blocks[x], 'contains', len(data), 'entries')
    if ipdict == 0:
        print('creating new dictionary')
        ipdict = {blocks[x]: data[:]}
    else:
        ipdict.update({blocks[x]: data[:]})
print('Dict has', len(ipdict), 'key(s) and ', sum(map(len, ipdict.values())), 'values')
