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. -David Schwartz > On Jul 9, 2023, at 12:33 PM, Keith Smith via PLUG-discuss > <plug-discuss@lists.phxlinux.org> wrote: > > 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.
