The Eagles were denied a perfectly good goal in the Championship clash at Bristol City on Saturday when the officials failed to spot the ball had entered the net, but bounced back with a well-earned victory at Portman Road.
Warnock said: "It was nice to get the disappointment and injustice of the weekend out of the way - not just by winning but playing as we did.
"We showed a great attitude, were solid at the back and inventive in midfield.
"I couldn't ask for more, especially at such a difficult place as Ipswich.
"It's been a weird feeling since Saturday. When you should win a game and an unfortunate thing like that happens, you can't get over it.
"But you have to put things in perspective and we only lost a game of football."
Warnock was full of praise for two-goal hero Darren Ambrose.
The former Town man scored twice in as many minutes after the break and then provided the cross for Neil Danns' third.
Warnock said: "I've always liked Darren and offered £1million for him when he was at Ipswich.
"He's drawn the short straw in the last couple of years but he was the first person who came to speak to me in the summer.
"I said he could be influential for me and score goals and he plays with a smile on his face.
"He's not worried about making a mistake because he knows he's not going to get a rollicking from me."
Ambrose's opener came after a cross from another former Ipswich striker, Alan Lee.
The Irishman centred from the right and Ambrose's far-post finish took a slight deflection to deceive goalkeeper Richard Wright.
His second, almost straight away, was a wonderful long-range effort that flashed inside the right-hand post.
Town were shell-shocked but pulled one back when Alex Bruce sent a bullet header past Julian Speroni after a pinpoint cross from Owen Garvan.
But Ambrose was not finished and his teasing cross from the right found Danns, who directed a header just inside the left-hand post.
Ipswich are still waiting for their first win of the season after losing at Coventry and being held to a goalless draw by Leicester on Saturday.
Town boss Roy Keane said: "I learned a great deal about my side and I know we've got a big challenge ahead, but then again I already knew that.
"When you concede three at home, you're always going to make life difficult for yourselves.
"It could have been more but then we could have scored more than one.
"In defence of the players, I take full responsibility.
"There were new players out there, young players and a new partnership up front.
"I know as well as anyone that sometimes these things don't happen straight away in football. It takes time to click.
"There are genuine reasons why we haven't hit the ground running and it would be very tempting to make excuses.
"In glimpses we looked dangerous but we expect better and the players demand better of each other."
