What frequency/LAN should I use?

OBSOLETE: This refers to the old packet network Since we have a subnet addressing system in use, we need to know what Local Area Network (LAN) you're going to use in order to issue the proper address. There are several ways you can determine which LAN is best for you. Probably the easiest way is to use your existing Terminal Node Controller (TNC) firmware to make AX.25 level connects to several of the stations on a given LAN. In particular try to talk to one of the gateway stations. Send several messages and verify that you have a good path for long messages. A good test is to issue several 'help' requests and monitor how well you receive them. If you find out that you have trouble, try another LAN if possible. Washington Area TCP/IP LANS

The following temporary IP addresses may be used for testing. You may use one or more of these until a permanent address is issued officially:


Use the appropriate subnet number for the LAN/subnet you will be testing on. Use these addresses at your own risk since someone else may have picked the same temporary number. Address numbers 44.24.[subnet].0 and 44.24.[subnet].255 are RESERVED for broadcast and network use, as per TCP/IP conventions.
