Keane has been without a job since being sacked by the Tractor Boys in January following a run of seven defeats in nine games.
The ex-Manchester United and Republic of Ireland midfielder had enjoyed a fine start to his career in the dugout by guiding the Blacks Cats to the Championship title in 2007 and keeping them in the top flight the following season, before standing down in December 2008 after a poor run of results.
And the 39-year-old believes he is capable of experiencing success again with the right club having learnt from his mistakes at Portman Road.
"I want a club to take to the very top," he told Irish radio. "Sunderland was so close, even in my third season there, just a few poor results which every manager goes through.
"I can learn from my mistakes, particularly at Ipswich, and I think potentially I could be a good manager. But potential is one thing, going out and doing it is something very different."
