IP address

[Salacious B Crum]

Installed a 10 gigabit dual port card in my unraid box I'm waiting on the 2 single cards for my R5 and R7 rigs making them peer to peer since a switch is stupid expensive so when it comes to assigning static IP addresses is there any rule to follow or can I just assign open IP's within my router network, I mean do they need to be sequential or in series or anything like that?

Nope, just need to fall within the same subnet mask and be outside the network range on your local network if they will only talk back to back.

So if you're using 192.168.x.y network then increment x by 1 and subnet mask should stay 255.255.255.0 if you want to keep it simple.

Ok I see that some use a whole different set of ip's such as 10.10.0.1 and so on if I understood it right this is so if your router assigns an ip address in its range that you applied to your peer to peer network there could be a conflict does that sound right? I mean of course the 10gb nic's are not going the be routed on my 1gb network through my router but was wondering if it will pose problems in the event that say one of my cell phones is assigned one of the ip addresses that is also part of my 10gb setup, make any sense?

You're DHCP range, the address pool from which the router will give out an IP address, for 99.99% of consumer routers is a /24 network. So if you increase the third octet, in this case X (a.b.X.z) by 1 over your existing network you won't have any conflicts. For IP addressing, to make it simple, a /24 is 256 addresses from x.x.x.0 to x.x.x.255 with 0 and 255 being not usable in this case. So increasing the third number by 1 will put it in a different subnet.

Assigning a static IP within a DHCP range can cause conflicts, correct. Assigning a static IP on a non-routed network (like your 10g network) to a phone or whatever won't yield any results as it won't be able to connect to anything as that range has no way to reach the gateway to the internet. 

 

Also, why would you place the 10g network in the same range as the 1gb network? It's not routable if it's peer to peer. Just pick a range with accompanying subnet mask, i.e. 192.168.69.x /24  (netmask 255.255.255.0), that's completely different from your routed network.

Ok got it waiting for the single cards the NAS sees the dual port ok
