VOITT, short for Virtual Operations, IT & Telecom, is an independent online project providing free tools and technical references for IT, networking, and telecommunications professionals. Its browser-based calculators and converters are designed to support common infrastructure tasks, with no registration required. The subnet calculator identifies network details from an IP address and mask, while the VLSM calculator helps divide a network into variable-size subnets. A bandwidth calculator estimates file-transfer time, and conversion tools handle number bases and data units, including bits, bytes, storage sizes, and network speeds.

VOITT also offers quick-reference material for everyday technical work. Visitors can consult TCP/UDP ports and associated services, HTTP status codes with descriptions, and an A-to-Z glossary of IT and telecom terminology. Its Insights section features articles on subjects such as artificial intelligence, telecommunications and global connectivity, and digital transformation. The project describes itself as independent and states that it is not affiliated with or endorsed by Voith GmbH & Co. KGaA or its subsidiaries.
