How paragraph numbers are read

I'd be glad if someone could tell me how numbers like "2.3.4.5.6" are read (pronounced)? "Two dot three dot four..." or "two three four" or maybe "two point three point four"?

The generally accepted and correct pronunciation of 2.3.4.5.6 would be:

Two point three point four point five point six.

The term point comes from full point as used as a punctuation mark or full stop. From Oxford English Dictionary (OED):

point, n.1

a. A full stop (in full, full point);

It seems that there isn't consensus on a single term to use.

In another post here on StackExchange, Dan Sheppard writes:

The word you use -- "dot", "point", "mark", "sub", -- is a matter of personal taste or else institutional style, but when in doubt a word which directly describes the symbol is usually fine (I would say point here).

Version numbers carry a similar ambiguity. Both the terms "dot release" and "point release" are valid, and version numbers can be read in a variety of ways. In the case of "Web 2.0," for example, both "dot" and "point" can be used:

There seem to be many possible ways of saying this - "two point oh", "two point zero", "two dot oh", two point nought", "two oh", "web two" - with a certain amount of variation according to nationality, company loyalties and other factors.
