- * Type 37 Address
- *
- * This address is named for the value of its AFI (37). This format
- * supports an X.121 address. A type 37 address has the following format:
- *
- * <----- idp -------> <- dsp ->
- * <- afi -> <- idi -> <- dsp ->
- * | "37" | 7 bytes | 9 bytes |
- *
- * The idi contains 14 bcd digits of X.121 address.
- * The use of the dsp part is unknown.
- *
- * The afi is considered the "network" portion of the address.
- * This means that you can't have multihoming in the x.25 environment.
- * Makes loopback a bear.
