The best chance of a forgettable 90 minutes saw Ipswich midfielder Guirane N'Daw's curling effort crash off the post early on and despite their best efforts Cardiff failed to score in a league game for the first time this season.
The leaders came into this match looking for a fifth straight league win but they were uncharacteristically subdued early on, captain Mark Hudson's wayward header from a long throw their only chance of note during the opening 25 minutes.
And they were inches away from falling behind to a spectacular strike from N'Daw in the 15th minute. The midfielder tried his luck with a 20-yard thumping left-foot drive that crashed off the woodwork with David Marshall beaten.
It took until the 27th minute for the Bluebirds to carve out another chance, Craig Conway firing over the bar after Craig Bellamy's pull-back was nudged into his path.
On the stroke of half-time Cardiff had comfortably their best chance of the match so far, Mark Hudson rising to meet Bellamy's ball with a looping header that dropped just past the far post.
Bellamy had the first chance of the second half. The Welshman's effort was well blocked by Luke Chambers when Craig Noone found him inside the box.
As the half wore on the home side began to up the ante with Peter Whittingham having a free-kick blocked and Aron Gunnarsson heading just over.
With eight minutes to go the visitors broke after a mistake by Andrew Taylor but the left-back quickly made amends, his outstretched foot diverting Carlos Edwards' shot over the bar.
Despite introducing both Tommy Smith and Heidar Helguson, Mackay's men could not find a way past a stubborn Ipswich side.
