Calc subredes: ferramenta interativa com visualização gráfica para o aprendizado de cálculo de sub-redes IP

Abstract

This work presents the development of CALC SUBREDES, an educational web tool for learning IP subnet calculations. The growing demand for connectivity and the scarcity of IPv4 addresses make mastering the subnetting technique essential to optimize IP address usage, reduce broad- cast traffic, and enable logical network segmentation. Although online subnet calculation tools exist, most use English and have a technical focus without pedagogical character, hindering conceptual understanding by students and beginners. The objective of this work was to develop an online tool in Portuguese, with an intuitive interface and graphical representation of subnets, facilitating the understanding of fundamental concepts. The adopted methodology consisted of technological development with bibliographical foundation and support in exploratory pedagog- ical diagnosis, used to identify recurring difficulties in the content and guide the survey of tool requirements. The system was developed using HTML, CSS, and JavaScript on the front-end and Python with Flask on the back-end, following the incremental development model. As a result, CALC SUBREDES offers a learning path with four content levels, automated subnet cal- culation, and graphical visualization of network topology, meeting the pedagogical requirements identified in the research.
