I don't know the "resolveip" tool (doesn't seem to be part
of FreeBSD), but obviously it interprets numbers that begin
with "0" as octal numbers, as is standard behaviour in C
and some other languages.

Given that, all of the above results are perfectly correct.

PS:  For quick conversion on the command line, I use dc(1):
$ dc -e 8i127p
87
$ dc -e 8o87p
127
