1. Write the Python object "switches" to YAML format 2. Transform "switches" so that it contains only "cisco" switches 3. Use the standard ipaddress module to get the last host address in the network "172.16.0.0/28" 4. Parse "dhcp_snooping_table" into a list of dictionaries of the form: dhcp_snooping_table_parsed = [ { "mac": "00:E9:BC:3F:A6:50", "ip": "100.1.1.6", "interface": "FastEthernet0/20", }, { "mac": "00:E9:22:11:A6:50", "ip": "100.1.1.7", "interface": "FastEthernet0/21", } ] 5. Write a class "NetworkSubnet" that has 2 methods: - get_subnet - returns the first available subnet of the specified length as an IPv4Network object - show_network_pool - returns a list of available subnets ```python from ipaddress import IPv4Network class NetworkSubnet: def __init__(self, aggregate_network: str): ... def get_subnet(self, length: int) -> IPv4Network: ... def show_network_pool(self) -> list[IPv4Network]: ... net = NetworkSubnet(aggregate_network="172.16.0.0/24") net_1 = net.get_subnet(length=26) print(f"{net_1=}") net_1=IPv4Network('172.16.0.0/26') print(net.get_subnet(length=25)) 172.16.0.128/25 print(net.get_subnet(length=30)) 172.16.0.64/30 print(net.show_network_pool()) [IPv4Network('172.16.0.64/30'), IPv4Network('172.16.0.72/29'), IPv4Network('172.16.0.80/28'), IPv4Network('172.16.0.96/27')] ```
