How do I write more than 254 addresses in ipv4 using only the quad?
(You get no / anything - - - - just the 4 quads! The idea is that these are all permanently set - - - not just flitting temporary demands a la Mikkie D's example.)
They are not permanent and as said, haven't been fixed block sizes for like 3 decades. Nothing wrong with 192.168.0.1 to 192.168.1.254 being one network. 192.168.0.255 and 192.168.1.0 are both valid addresses in 192.168.0.0/23 subnet. In 192.168.0.0/24 192.168.0.255 would obviously not be a valid address. Every device that allows an IP to be entered also has either a netmask (which you can set to 255.255.254.0 for /23) or has the /23 notation available. -- Len Sorensen
