I have a simple query, on E.164:
Steps to E164.arpa:
1. See that the E.164 number is written in its full form, including
the countrycode IDDD. Example: +46-8-9761234
2. Remove all non-digit characters with the exception of the leading
'+'. Example: +4689761234
3. Remove all characters with the exception of the digits. Example:
4689761234
4. Put dots (".") between each digit. Example: 4.6.8.9.7.6.1.2.3.4
5. Reverse the order of the digits. Example: 4.3.2.1.6.7.9.8.6.4
6. Append the string ".e164.arpa" to the end. Example:
4.3.2.1.6.7.9.8.6.4.e164.arpa
Query:
1) Why are we using the number in reverse order ? What was the idea behind reversal of number .
2) Why can't we send the digits without "." dot. The RFC's explain the behaviour of it, but not the concept behind the reversal and insertion of dot in the numver
Will look forward for your reply.
