'contribution to online address' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'foremost dons moaned about' is the wordplay.
'foremost' becomes 'main' (I've seen this before).
'dons' indicates putting letters inside (don means to wear or put on).
'about' indicates anagramming the letters.
'moaned' is an anagram of 'doname'.
'main' put within 'doname' is 'DOMAIN NAME'.
