🚀 We just launched a free network engineering toolkit — no login, no paywall, no bull.
interconnectedsystems.net/#t…
We built this because we kept reaching for scattered tools across a dozen different sites. Now everything's in one place,
purpose-built for network engineers, sysadmins, and IT teams.
Here's what's included:
━━ IP & SUBNETTING ━━
📐 IPv4 & IPv6 Subnet Calculator — network, broadcast, first/last host, usable IPs
🔄 CIDR ↔ Subnet Mask Converter — with wildcard mask
🔢 IPv4 ↔ Binary/Hex Converter — per-octet breakdown
📦 IP Range → CIDR Blocks — converts any range to minimal CIDR blocks
📡 Traceroute / MTR — server-side hop-by-hop path trace with IPv4 & IPv6 support
📍 IP Geolocation — ASN, org, city, region, timezone via IP or hostname
🔌 TCP Port Scanner — CAPTCHA-protected, abuse-resistant server-side scanner
⚡ Bandwidth Calculator — bps to Gbps, plus file transfer time estimates
🌐 My IP — detect your public IPv4 and IPv6 simultaneously
━━ BGP / ASN ━━
🔍 ASN Lookup — holder, announced prefixes, active routes via RIPE Stat
📋 BGP Prefix Lookup — block name, origin ASN, announcement status
🗺️ IP → BGP Route — find the BGP route covering any IP address
━━ DNS & LOOKUP ━━
🔎 DNS Query — A, AAAA, MX, TXT, NS, CNAME, SRV, CAA and more via Google & Cloudflare DoH
↩️ Reverse DNS (PTR) — IPv4 and IPv6 reverse lookup
🌍 DNS Propagation Checker — compare Google vs Cloudflare for any record type
📧 Email Security Analyzer — MX, SPF policy, DMARC enforcement in one query
🔐 DNSSEC Validator — checks DS, DNSKEY, and AD bit validation
━━ WIRELESS ━━
📶 Free Space Path Loss (FSPL) — Friis equation for any frequency and distance
📡 EIRP Calculator — Tx power antenna gain in dBm/dBi/W/mW
🔗 Link Budget — full path analysis with Rx sensitivity and margin
📊 Signal Quality Estimator — maps dBm to RSSI rating and quality tier
📋 Wi-Fi Channel Reference — 2.4 GHz, 5 GHz, and 6 GHz channel tables
━━ VOIP ━━
🎙️ Codec Bandwidth Calculator — per-call and N-call bandwidth for G.711, G.729a, Opus, iLBC, and more
📈 MOS / E-Model Calculator — ITU-T R-factor and MOS score from codec packet loss latency
🎹 DTMF Tone Reference — all 16 DTMF frequencies with interactive keypad
📡 SIP Response Code Reference — full 1xx–6xx code table with descriptions
━━ ROUTING & EVPN REFERENCE ━━
📚 OSPF — LSA types 1–7, area types, DR/BDR election
📚 BGP — iBGP vs eBGP, path selection, communities, route reflectors
📚 IS-IS — NET addressing, L1/L2, TLVs, redistribution
📚 MPLS & SRv6 — label operations, SID behaviors, segment lists
📚 EVPN & VXLAN — route types 1–5, MAC/IP advertisement, BUM handling
Everything runs in your browser or server-side. No account required. No data stored. It will save you time!
