You mean you have
>>> import ipaddress
>>> n = ipaddress.ip_network("192.168.1.128/25")
>>> n
IPv4Network('192.168.1.128/25')
? Then one
>>> dir(n)

'_version', 'address_exclude', 'broadcast_address', 'compare_networks',
'compressed', 'exploded', 'hostmask', 'hosts', 'is_global', 'is_link_local',
'is_loopback', 'is_multicast', 'is_private', 'is_reserved',
'is_unspecified', 'max_prefixlen', 'netmask', 'network_address',
'num_addresses', 'overlaps', 'prefixlen', 'subnets', 'supernet', 'version',
'with_hostmask', 'with_netmask', 'with_prefixlen']
later:
>>> n.network_address
IPv4Address('192.168.1.128')
