are there any definitive (or jsut about standard) IPs i know will be a lan IP? this is to make my app, internet only or LAN only.
my code currently cycles through the h_addr_list and checkin the first 3 characters to see if they are LAN ips.
writing network apps without a LAN sucks :(
Search: private ip address ranges
well i had already got 10. 192. and 172. , but friend of mine said one of his IPs was 169. i just found out that was a default one so that would mean:
10.0.0.0
172.16.0.0
192.168.0.0
169.0.0.0
are all LAN adresses?
can i just assume that anyone daft enough to use a public IP for their lan is too stupid to use my app :p
169.254.*.* is not a LAN IP address. It's used when the OS is set to use DHCP but cannot find a DHCP server.
in any case it's not a net address then
thank you people :)
For the 172 range, it's actually 172.16.0.0 - 172.31.255.255.
I thought the 10.*.*.* range was something special also..?
