[[
While c is not the EOF code point, run these substeps:

    Let value be 0.

    If c is not an ASCII digit, parse error, return failure.

    While c is an ASCII digit, set value to value × 10 + c interpreted as decimal number and increase pointer by one.

    If value is greater than 255, parse error, return failure.

    If dots seen is less than 3 and c is not a ".", parse error, return failure.

    Set piece to piece × 0x100 + value.

    If dots seen is 0 or 2, increase piece pointer by one.

    Increase pointer by one.

    If dots seen is 3 and c is not the EOF code point, parse error, return failure.

    Increase dots seen by one. 
]]

This allows less than four decimal parts (three dots), eg: http://[::168.0]/

It probably should not.
Comment 1 Anne 2013-12-04 14:58:00 UTC 
Is something incorrect with the dots seen check?
Comment 2 Simon Sapin 2013-12-04 15:01:27 UTC 
It’s already correct, I misread it.
