What is CIDR?
Classless Inter-Domain Routing, also known super-netting, is used to reduce the size of routing tables and to increase routing speeds. By grouping subnets together, a single route can be entered for several destinations. A router in the Autonomous System that the destination belongs in will then determine the final route.
What is my default gateway address?
The default gateway address for devices on your LAN allows your local devices (such as PCs and servers) to recognize where to send information destined for the Internet.
Why can't I use the first and last IP addresses on my subnet?
The first and last addresses are reserved on any network. The first address is the network address which is reserved for the physical network. The last address is the broadcast address which is reserved to send to all devices on the network.
I have registered my own IP addresses. Can I reuse these?
Yes, the IP addresses that your company has registered with the ARIN (American Registry for Internet Numbers) are usable on your network. You must order part number INST-ROUTE for them to work correctly. Please contact your Sales Representative for more information.
I'm considering a redundant link to the Internet. How do I configure this?
G4 Communications uses BGP to update its routing tables. This protocol also allows multiple links to the Internet. If you are interested in this service, contact your Sales Representative.
Can I use my own routers?
G4 Communications does not support routers that are not recommended or configured by G4 Communications personnel, however there is no limitation to using your own routers on your network.
Can I have static routes entered for my internal network?
If you have networks beyond your local router that need access to the Internet through your router, then routes will have to be entered for you. Please call the Technical Assistance Center at 1.888.840.4487 to discuss your needs.
Can I use RIP, RIP II or OSPF to exchange route information with G4 Communications?
No, G4 Communications does not use routing protocols on our network. However, you may use these internally to update your local networks.
