EyePee-O-Matic

EyePee-O-Matic: The Network Tool Built for Live Audio Stop wrestling with subnet math. EyePee-O-Matic gives you instant, accurate IP calculations so you can focus on making shows sound amazing. Built by audio engineers who've configured countless Dante networks, planned touring rig IP schemes, and explained to IT departments why 169.254.x.x addresses are completely normal. WHY AUDIO ENGINEERS LOVE IT - Calculate subnets for consoles, stage boxes, and wireless systems - Plan network segments before you arrive at the venue - Validate IP schemes before soundcheck - Detect subnet overlaps that could kill your show - Learn the "why" behind every calculation NEW: AUDIO INDUSTRY GLOSSARY 21 terms covering everything AoIP engineers need to know: DANTE Self-assigned IPs explained. Why Audinate recommends 169.254.x.x for most deployments. How to set up redundant networks (Primary: link-local, Secondary: static 172.31.x.x). MILAN & AVB/TSN Deterministic audio transport, IEEE standards, and why certified switches matter. PTP vs gPTP vs MEDIA CLOCK The critical distinction: PTP answers "what time is it?" while the Media Clock answers "how long is 1 second?" Finally understand why these are different. LINK-LOCAL (169.254.x.x) Not a DHCP failure. Not a broken network. This is Dante working exactly as designed. Show this to your IT department. Plus: CRF, QoS, VLAN, AoIP, and more. COMPREHENSIVE TOOLS Subnet Calculator Enter any IP and CIDR prefix. Get network address, broadcast, usable range, and host count instantly. Step-by-step explanations show the math. Network Planner Wizard-based planning for entire show networks. Add your device groups, get optimized subnet allocations. Export as Text, CSV, or JSON. VLSM Calculator Variable Length Subnet Masking for efficient IP space. Different subnets for consoles (10 hosts), stage boxes (50 hosts), and wireless (20 hosts). Host Requirements Need exactly 100 devices? Calculate the perfect prefix length. See efficiency metrics and wasted addresses. Overlap Detector Check if two subnets conflict before deployment. Critical for avoiding "why did the network just die?" moments. Subnet Divider Split a /16 into eight equal /19s. Power-of-2 divisions for clean network segmentation. Range to Subnet Got an IP range from your network admin? Convert it to proper CIDR notation. Supernetting Aggregate multiple subnets for efficient routing tables. Wildcard Calculator Convert between subnet masks, prefix lengths, and wildcard masks. Essential for ACLs and firewall rules. IP Validator Validate addresses and see classifications (private, public, multicast, link-local). Binary, hex, and decimal representations. Address Converter Switch between dotted decimal, binary, hex, and decimal formats. Copy with one tap. LEARN & PRACTICE - Interactive tutorials on bits, binary, and subnetting fundamentals - Common subnet reference table - Practice mode with instant feedback - Step-by-step calculation explanations PROFESSIONAL GRADE - No ads. No subscriptions. No data collection. - Works offline - perfect for venues with no internet - Universal app: iPhone, iPad, Mac, Vision Pro - Family Sharing enabled - RFC 3021 /31 point-to-point support PERFECT FOR - Live sound engineers - System integrators - Broadcast engineers - AV installation technicians - Anyone configuring Dante, Milan, or AES67 Whether you're planning a festival's worth of Dante endpoints or explaining VLANs to a venue's IT manager, EyePee-O-Matic has your back.
