Core Python Programming . . .

[FireNWater]

I'm working my way thru the book "Core Python Programming" 2d Edition
- Wesley Chun. . .

Trying to figure out what he's looking for on Page 248, Exercise 6-11
(a).

Is it supposed to be:

1) convert a 4-digit Integer (WXYZ) to an IP address (WWW.XXX.YYY.ZZZ)

or

2) convert an 8-digit Integer (WWWXXXYYYZZZ) to (WWW.XXX.YYY.ZZZ)

Thanks for anyone with the clue!!!

Without being able to see the exercise I suspect it's turn a 4-byte
string (i.e. 32 bits) into an IP address (int8.int8.int8.int8).
Or, it might be turn a 32-bit int into such an address.

I've got the book and I think the OP may be referring to this:

6-11 Conversion.
(a) Create a program that will convert from an integer to an
Internet Protocol (IP) address in the four-octet format of WWW.XXX.YYY.ZZZ
(b) Update your program to be able to do the vice verse of the
above.
It could be a 12 digit int...or it could be what you (Paul) are
referring to.

I think it's is asking to convert a 32-bit int to the dotted form.

It's a little known fact, but IP addresses are valid in non-dotted
long-int form. Spammers commonly use this trick to disguise their IP
addresses in emails from scanners.
