- Lines: 46

- Dear Netters,
-
- We have problems with some legal IP network numbers which NSFNET
- refuses to put them in the core gateway. Why? We have been allocated
- several dozen class B and over 200 class C network numbers. And the
- authority for the NSFNET refuses to put most of the class C network
- numbers in the core gateway. Does that mean we can't use those network
- numbers?
-
- I have a solution to this problem though not good :
-
- 1. Spilit our network into two topological parts, A for networks
- with their network numbers registered in NSFNET and B for
- those not registered in NSFNET.
-
- 2. Set up two mail gateways, Gin and Gout, in part A.
-
- 3. Allocate a dummy domain, dummy.TW, for hosts in part B.
-
- 4. Add only a MX RR for dummy.TW such as "*.dummy.TW. MX 0 Name-for-Gin"
- in the name server for domain TW.
-
- 5. Set up a bogus root name server in part B containing a lot of MX
- RRs for domain Edu, Com, Net,... as follows:
-
- *.Edu. MX 0 Name-for-Gout
- *.Com. MX 0 Name-for-Gout
- *.Net. MX 0 Name-for-Gout
- .
- .
- .
- *.Edu.TW MX 0 Name-for-Gout
- *.Gov.TW MX 0 Name-for-Gout
- *.Net.TW MX 0 Name-for-Gout
-
- 6. Gin query the bogus root name servers in Part B and Gout query the
- normal name server in Part A for resolution. Then Gin will forward
- mails to hosts in Part B, and Gout will forward mails to the
- outside world.
-
- 7. Hosts in Part B can still access (telnet, ftp, ...) hosts in Part
- A (not the whole Internet) by IP address and vice versa.
-
- Any suggestion or comment will be very much appreciated.
