awk weird problem.

awk 'BEGIN{print}'

Can anyone explain why has extra "0" in the IP address?

Because it's printing the concatenation of 3 floating point numbers: 1.2, 0.3, and 0.4. If you want to print the ip address, quote it so that it's parsed as a string.

but why awk think that's 3 floating numbers, not a string? Is the bug in it?

$ awk 'BEGIN{print ""}'
