In case of using this flag, that will raise the following exception:
>>> netaddr.IPAddress("200a::1", flags=netaddr.core.ZEROFILL)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.10/dist-packages/netaddr/ip/__init__.py", line 333, in __init__
    self._value = module.str_to_int(addr, flags)
  File "/usr/local/lib/python3.10/dist-packages/netaddr/strategy/ipv4.py", line 120, in str_to_int
    addr = '.'.join(['%d' % int(i) for i in addr.split('.')])
  File "/usr/local/lib/python3.10/dist-packages/netaddr/strategy/ipv4.py", line 120, in <listcomp>
    addr = '.'.join(['%d' % int(i) for i in addr.split('.')])
