Lee Croft's stunning strike set Norwich on course for glory in the 90th East Anglian derby to give manager Glenn Roeder a vital win at the foot of the Coca-Cola Championship.
Croft dispatched an excellent strike from 25 yards to cap the game's best move and relieve the pressure on Roeder.
Matty Pattison then lashed in a second late on to give the Canaries their first taste of derby success in six attempts.
Last year's corresponding fixture was Roeder's first game in charge and despite a huge turnover of players in the summer the Canaries entered this clash 13 months on still struggling.
A poor start to the season saw them kick-off just two points above the relegation zone but a strong performance saw them deservedly take all three points.
Leroy Lita should have opened the scoring in the ninth minute but he planted a free header from David Bell's corner straight at Richard Wright.
The on-loan Reading striker looked sharp and it required an excellent challenge from Ipswich captain Gareth McAuley to deny him a shot minutes later as the game continued at a frantic pace.
Alex Bruce then headed over at the other end before the Canaries rattled the woodwork. Sammy Clingan chanced his arm with a long-range strike which struck Bruce and arced over Wright but on to the top of the crossbar.
Croft opened the scoring in the 60th minute when after Pattison and Wes Hoolahan played a smart one-two on the left touchline Croft picked up the ball then took one touch before blasting his shot into the top corner from 25 yards.
And the the home side grabbed a second goal in the 82nd minute. Bell's free-kick was not cleared and Pattison hammered a shot in off the underside of the crossbar.
