Which syntax should I use if 1.3.6.1.4.1.1466.115.121.1.27 is not big enough?

1.3.6.1.4.1.1466.115.121.1.27 "INTEGER" has no size limits.

OTOH there's a configurable limit to how big integers can usefully indexed. Integer indexes switch to a floating format for integers that do not fit in around 2**30 (IIRC). If you have a bunch of integers 100000000000000000000 +/-10000 and want to search for them, you need to increase index_intlen so they don't all get the same index key.

1.3.6.1.4.1.1466.115.121.1.36? (I don't see a kind of big integer)

Numeric String? There are times when that makes sense, e.g. you can use Substring search and substr index. Or if you want to preserve leading zeroes. Typically for IDs which are really just strings which may only contain digits. Otherwise not.
