Most consumer routers won't, but the nice part is most older router hardware *can* typically run ddwrt/openwrt that will.  I often see decent older routers at goodwill and thrift shops, or always ebay if you have a hardware platform you want to target.  Ideally find one that is dual core, decent memory, ideally a usb 3.0 port for shenanigans, and most should be capable of modern internet speeds.

If nothing else, any moderately non-decrepit x86 boxes can run pfsense/opnsense too easily enough to do this too.  I have run everything from cisco, palo alto, fortinet, *wrt's, etc as a firewall both in customer enterprises and my house, and so far my current opnsense has become a favorite.  Certainly not a full replacement for enterprise features you get out of the big names, but the best blend of features for both consumer and enterprise-y features.

I would ask the question of why you *really* need multiple ip addresses to begin with.  For all my shenanigans replicating enterprise features at my house in 25 years, I've never needed multiple ip having hosted at times everything from web servers, vpn, email, and everything else in between, even when I worked for Cox and could for free.  Between crafty uses of NAT, DNS, and Certificates using proper SAN's, there's very little reason to *need* to more than usually folks just *want* to or don't know better aforementioned methods.

others here are correct cheap consumer routers rarley have the option to handle multiple ip's
better routers do. It is built in ipfire ( my choice of routers) on a old computer with 2-4 network cards or in a vm also works and I think it is available in
pfsence or opensence and DDWRT just add a alias IP and then port forward to the server you want it togo to.

Buddy who ran cox business had 6 ip's.  stacked them on the router and provided different SNAT/DNAT to the boxes behind.  There was some configuration fiddliness with the modem, but this was years ago.  any reasonable router would be able to do this, the main question is how the modem handles it.

AFAIK, the Cox router can be configured to either run DHCP or as a Static IP address. Either way, it can only listen to one IP. They do run DHCP from the local hubs, but the IPs themselves rarely change, and you’re sharing them with the whole neighborhood.

Most hosting providers share a single IP among multiple accounts coming into a server. There are two separate IPs for DNS hosting on a totally different server. If you want your own dedicated IP for your account, you can usually get it. But I can’t think of any that let you set up a separate IP for individual services unless they’re on separate servers in different facilities. I’ve had hosting accounts where they share a pool of IPs among hosting accounts, and I’d have up to 6 IPs, but each account only had one IP and all of the services used that one IP.

The only situations I’ve heard where people are using multiple IPs is to have backup internet providers, like Cox, CenturyLink, etc, in case one of them goes down. In those cases, you need a router designed to handle multiple (usually two) WAN ports where one is primary and the other is a failover.

Hi,

Was looking at the raspberrypi this morning and it brought me to the same place I have come to several times in the post.

I have a business account with Cox Cable which allows me to run 1 or more servers.  Last year I used an old laptop to make a web server using Ubuntu, Apache, MySQL, PHP, plus Postfix and dovecot, plus BIND.  I'm a PHP dev so I felt pretty good about that achievement.

I only have 1 public IP and everything on my network has a private IP.  I used port forwarding to get the web server to work.

Supposedly I can get multiple IPs from Cox.  On several occasions I've asked the level 1 how I would configure 1 or more servers on the public IPs they can provide and they do not know how.

At some point in the future I'm thinking I'd like to create a publicly facing group of PIs to run as a web server (or maybe more)... 1 for HTTPS, 1 for DNS, 1 for mail, and 1 for MySQL (on a private IP ?).

I assume I would use the Cisco gizmo that has coax in and RJ45 out... the out would go into a small switch which would route each IP to the appropriate PI based on the BIND config.  I assume I can plug my Netgear router into the switch that currently has multiple devices connected to it on private IPs, and which provides WIFI.

I assume I can add a router in between the Cisco (modem?) and my Netgear and everything would work as it does now.  The added router would then be in place to deal with any additional IP address that Cox would provide?

Thanks in advance for any help!!

Keith
