This is why it is by far safer to use the latin species name.
Just like everyone else, this is a Boa Constrictor Imperator (latin scientific name). It's unclear what locality it might be.
Boa Constrictor Imperator (BCI, "common" boa) specimens tend not to have bright red tails... they tend to be more orangey or brownish, though some can have reddish tones.
Boa Constrictor Constrictor (BCC, "redtail" boa) specimens usually have blood red or deep brownish red tails.
BCI and BCC can breed together, so there are mutts out there as well that might be hard to categorize.
BUT - just goes to show that common pet names can vary from place to place, and when in doubt, ask for the SPECIES name.
