Given my background in Computer Science and work experience, what Master's specializations in Belgium or Ireland would focus on advanced software development, data science, machine learning, or network security, and require an IELTS score of 6.5 or higher?

Your background lines up well with named programmes in both countries, but each university weighs your exact 2.1/2.2 percentage and work experience differently, so the right shortlist depends on how competitive your transcript is, not just IELTS.

Ireland: Four Programmes Worth Shortlisting

• TU Dublin, MSc Computer Science (Advanced Software Development): IELTS 6.5 overall, 6.0 in each band. Normal entry is a 2.1 CS/Computer Engineering degree, or 2.2 plus at least two years of relevant work experience, a route that suits your profile directly.
• TU Dublin, MSc Computer Science (Data Science): same IELTS requirement, and the same 2.2-plus-experience entry route applies if your work involved programming, SQL or analytics.
• University of Galway, MSc Computer Science (Artificial Intelligence): IELTS 6.5 overall, 6.5 in Writing, 6.0 in other bands.
• University of Galway, MSc Computer Science (Adaptive Cybersecurity): same English requirement as the AI programme.

Belgium: A More Research-Oriented Route

KU Leuven's MSc Engineering: Computer Science is the standout option, with six specialisation tracks including Artificial Intelligence, Secure Software, Software Engineering and Distributed Systems, all built on a core of software development, architecture and machine learning. Its published English requirement is IELTS Academic 6.5. The University of Antwerp's MSc Computer Science: Data Science and Artificial Intelligence is a strong alternative, requiring IELTS 6.5 overall with at least 6.0 in each component, while ULB offers a dedicated MSc Cybersecurity for the network-security direction specifically.

Matching Your Work Experience to a Track

Software development or backend work points toward Advanced Software Development or Software Engineering; Python plus SQL and analytics points toward Data Science; networking, Linux or DevOps experience points toward Cybersecurity or Secure Software.

My Advice

Lean on your work experience explicitly in your application if your undergraduate percentage sits at 2.2 rather than 2.1, TU Dublin's stated alternative entry route rewards exactly that combination, and it's a genuine admissions lever most applicants don't use fully in their SOP.
