Static and Dynamic IP Addresses
- Ability to host your own web, mail, or game server at your home or office
- Always know what your IP address is, in case you need to access your home computers
- Cheaper initial network equipment cost
- Home networking flexibility
- Greater compatibility with VPN networks
- Easy access to multicast content
The illustration to the right shows a network configuration that is only possible with multiple static IP addresses. Four devices are connected to an ethernet switch or hub, each with its own static IP. This type of network would be possible with any Sonic.net broadband product with at least four static IPs. (1) is a typical web server, (2) a workstation, (3) a game console, and (4) is a wireless router, set up to offer Internet connectivity to wireless clients.
In this configuration, the DSL bridge/modem should be connected to your switch or hub, and any locally connected computers (PCs, Macs, Xbox, etc) can be directly connected to this switch. DHCP is offered, so you can either set the addresses of these systems static, or use DHCP on all systems.
Easier to set up than with dynamic IP.
Public addressing make remote access simpler.
No SOHO router conflicts, as there is no need for a SOHO router.
The illustration to the right shows a network configuration that is possible with either static or dynamic IP addresses. Three devices are connected to a SOHO router, each obtaining a local IP address via NAT. (1) is a typical web server, (2) a workstation, and (3) a game console. Unlike the previous example, the devices on this network are not directly-addressable from the rest of the Internet.
In this configuration, the DSL bridge/modem should be connected to your router, and any locally connected computers (PCs, Macs, Xbox, etc) can be directly connected to this router. DHCP is offered at Sonic.net, so you can let the router automatically discover its own public address.
Hosting your own web, mail, DNS, or application servers on a dynamic-IP product presents a number of configuration problems. First, as your public IP address changes from time to time, it is more difficult for hosts outside your local network to find your server or servers. Dynamic DNS services (not available directly through Sonic.net at this time) can address this, but may also entail their own reliability issues. Hosting multiple computers on a single IP address — dynamic or otherwise — requires the use of a router to act as a go-between on the network. Many routers can be configured to direct certain types of traffic to specific local computers, but this process can be complicated and may require retaining the services of a networking specialist..
There are many reasonably user-friendly SOHO routers on the commercial market, making it easier than ever to connect multiple computers to a single-IP broadband connection. With many brands you simply need to plug the various computers into the router, and then the router into your DSL modem in order to share your connection. Remote management of workstations can be tricky due to a lack of a persistent, public address, necessitating more complicated configuration changes to your SOHO router.
Sharing a Dynamic-IP connection between multiple game consoles, or between a game console and other devices such as a PC, requires a router. Many console games work without special configuration through typical SOHO routers, but others may experience networking difficulties that have to be addressed through advanced configuration changes made to the console and to the router.
