Integer overflow most likely occurs during calculations that exceed storage limits. When a program attempts to store a value in a data type that cannot accommodate it, the data can wrap around, leading to unexpected results. This scenario commonly arises in situations involving arithmetic operations, where the results can exceed the maximum representable value of a particular integer type.

For instance, if a variable defined as a signed 8-bit integer tries to hold a value larger than 127, the result will not be the expected value but rather a negative number or a much lower positive number due to wrapping. This can cause significant issues, such as vulnerabilities in software that can be exploited by attackers.

The other scenarios, such as network traffic analysis, displaying text, and web-based applications, typically do not involve arithmetic operations that are likely to lead to integer overflows. While issues can arise in these contexts, they are not primarily associated with the overflow of integer values during calculations.
