Town have banned a supporter from this season's remaining matches both home and away for racially abusing a Brighton fan on Twitter.
The 17-year-old made the comments on Saturday after the Blues’ 3-0 defeat to the Seagulls and was subsequently interviewed by both the club and the police.
Town chief executive Simon Clegg told the club site: "There seems to have been a recent resurgence of homophobic and racist issues within football and as a club we are absolutely committed to supporting the Football Association and Football League in helping to stamp these out.
"Football is a game of passion both on the field and off it but we will not hesitate to take action against any individual associated with this club who is involved in inappropriate behaviour.
"Ipswich Town fans have an excellent reputation at home and away and I'm determined that the good name of the majority is protected."
Shortly after the offensive Tweet was was made, the account was removed.
