i need to determine ips needed, subnet mask for lans and wan, and network address, first usable ip and second usable ip

Requirements - Make hostnames for routers match the display names in the topology diagram (Valley for example). Note that host names ARE case sensitive and that there are no numerals or spaces in router hostnames. - Do not change host names for PCs or Switches - All routers require a Banner MOTD - Create your own warning/banner - Do Not put passwords or secrets on any router - Create LAN networks (subnets) that are sized so that no IP addresses are wasted (except as needed by the constraints of binary math), but where all nodes can receive a valid and unique IP address - Create WAN networks that are sized so that no IP addresses are wasted (except as needed by the constraints of binary math), but where all nodes (router interfaces) can receive a valid and unique IP address - Important: There must be no IP Address overlaps, and you may not, under any circumstance use any IP addresses that are not included by the WAN and LAN blocks of addresses in the Specifications section above - Configure all router LAN IPs based on the addressing scheme in the specifications above and subnet masks that you determine as part of the address allocation - Configure IPv4 for all PCs and the two servers (www and Files) based on the addressing scheme in the specifications above with the following information - IP Address: The second usable address on that network - The proper subnet mask - The proper default gateway address - All PCs should be able to ping all other PCs - You should be able to use a web browser and receive the page from the www server using its IP address As a reminder: LAN Address block is 91.32.32.0/23 WAN Address block is 192.168.34.16/28
