Well that's a 'feature' of ping that I never knew about. It appears that if the individual octets of an IP address are assumed to be in decimal if they begin with any digit other than zero, but when they start with a zero ping is treating them as Octal (BASE 8) numbers. 010 (base 8) = 8 (base 10), 011 (base 8) = 9 (base 10), and 017 (base 8) = 15 (base 10). Weird behavior and nothing to do with the 'octets' as such - which are so named because they consist of 8 bits each.
