[TWC] Static IP ideas for home network

Technically you cannot get an static IP. But on the other hand. Time Warner uses the Hardware mac address to authorize/function on there networks. As long as you do not do hardware changes IE: Router, Network Interface card. the ip pretty much does not change. On occasion they might push a ip change, but those are far and few between.

I speak from experience the ip is dynamic but rarely changes.

What do you need the static IP for? It helps in getting you setup perfectly.

Yes the router will need an IP.

i want to assign static ips to better manage my network and topology.

would i be able to assign static ips without a problem using a router in the middle?

what the router i mentioned work well with my intended use?

reply to iPenguin02
WAN side you'd need a business account, public IP issued to the modem by TWC.

From your explanation you just want devices within your network to have a static IP? A router would be able to assign devices by mac address a static private IP. (192.168.X.X)

reply to iPenguin02
yes just for my lan. i plan on using 172.16.x.x network. so the router i intend on getting will work fine with assigning my network static ips within my lan

reply to iPenguin02
Static PUBLIC IP? not going to happen on a residential account. You can get more than one *dynamic* address, but again, they're dynamic and can change.

If all you want is static internal addresses, there's nothing in the world stopping you from doing that. Assign a machine an address and enter it into the appropriate network configuration widget. If you're talking about mobile devices (cellphone, tablet, laptop, etc.) that need to use DHCP, then you need something that can provide "sticky" DHCP assignments. I'm not familiar with the 6580's DHCP engine, but I don't see why it wouldn't support this.

172.16 is a private ip range.

and yes thats what i want to do private internally. i cant use the sbg6850 to assign static because rr wont support it. thats why i asked if a router in the middle will be able to do so without causing any problems.

The asus can assign statics, why the 172 vs 192?

reply to iPenguin02
Wouldn't having TW put the SBG6850 into bridge mode do what you want. The router will get the pubic ip address then you can assign your LAN however you want.

reply to Jabbu
just personal preference? do you have a reason why 192 is better suitable?

The SBG6850 will not allow me to assign static IP's to my internal network apparently not allowed.

How would i set up both the modem and the asus to work correctly?

If i assign my sbg6850 172.16.1.1 do i leave DHCP on? what do i do with the DHCP settings? Starting IP? and CPE's?

Would i assign the Asus 172.16.1.2? then assign all devices on the network anything above?

Should i also disable wifi on the SBG6850 and just use the asus?

any other suggestions on how to get this to work?

Call TWC and ask for your modem to be placed into bridge mode, if the person you are speaking with is unsure of this, ask for tier3.

You could also try google and do it yourself.

I was just curious why you choose 172, no difference in a small home lan.

Once the SBG is in bridge mode, its DHCP and wifi is turned off, handing a public IP off to your asus, your asus will then handle your static LAN IPs, set the asus as 172.16.1.1.

Once you bridge the sbg, it is just a modem, no settings to worry about.

I use 172 at home because it's an easy, quick way to know I'm connected to MY network vs my neighbors vs some default config stuck in the device.

Find out what your router's DHCP scope is and then assign IPs that are out side of that scope. You should be able to change the range of DHCP addresses so that you can have both static and dynamic IPs on your network.

I've got all of my switches, APs, phones, NAS, servers etc on my LAN setup with static IPs then I allow Laptops, Tablets, Consoles, Phones, etc to pickup an address via DHCP.

If there are no devices other than the router you want on the LAN between the Modem's LAN and the Router's WAN then just assign an IP even if it's in the DHCP scope. IF there are never any devices on the modem's LAN then there will never be a request from the DHCP server so you won't see any IP conflicts.

Jabbu thanks for the advice that seems like the easier route to go down.

So once they turn the SBG into bridge mode. The Asus would be my default gateway? and everything would be setup in there.

That kinda sounds too good to be true. hope it works
