Russian translation of the "range" term?

[Ivan Kazmenko via Digitalmars-d-learn]

Hi!

I'm unsure what is the Russian equivalent for the term "range", 
as in "D range", the generalization of a pair of iterators.  With 
"range" being such an overloaded term in source language and 
having no exact equivalent in the target language, its Russian 
translations I have come up with don't sound quite right.

Is there an "official" translation already?  In TDPL, the (very 
few) occurrences of "range" are translated as "диапазон" 
(Cyrillic for "diapason"), how official is that?  In Russian, the 
term "diapason" in computerspeak is used to refer to a range of 
possible values, as in "the range (diapason) for an ubyte 
variable is from 0 to 255".  Also, it has four syllables, making 
it long-ish to pronounce.

The original article "On Iteration"[0] suggests that the name 
"iterator" would also fit if it was not so heavily used, but in 
Russian, we also have that loan word with the same meaning and 
usage already.

I guess synonyms or translations into other languages with some 
interlingual explanations could also help.
