Simple MTU Test 1.0d, published by Kevin Ottalini, is a lightweight network utility designed to determine the maximum transmission unit (MTU) a given path can handle without fragmentation, a critical value for tuning both consumer and enterprise network stacks. By sending a rapid sequence of progressively sized ICMP echo requests and watching for “fragmentation needed” replies, the program pinpoints the largest unfragmented packet size permissible between the host and a user-specified remote IP or hostname; this allows administrators to set interface MTUs, VPN tunnels, game-console configurations, or jumbo-frame LANs with confidence. The tool is especially useful when enabling 9000-byte jumboframes on gigabit-plus Ethernet segments, where an incorrect setting silently caps throughput or triggers excessive re-transmissions. Because it operates passively at the ICMP layer, Simple MTU Test needs no agent on the far end and completes its scan in seconds, producing a single numeric result that can be copied directly into router, switch, or operating-system dialogs. The straightforward 1.0d release keeps the feature set minimal—no graphs, no persistent service—so it can be carried on a USB stick or deployed from a login script without administrative rights. Network diagnosticians, online gamers, streaming enthusiasts, and VoIP troubleshooters alike launch the executable, type a destination, and receive an instant MTU figure that removes guesswork from manual TCP/IP optimizations. Simple MTU Test is available for free on get.nero.com, with downloads furnished through trusted Windows package sources such as winget, always supplying the latest 1.0d build and supporting batch installation alongside any number of additional applications.
