Network tools
Focused tools that answer one question each and explain the answer. No account, no stored history.
Connection & Wi-Fi
How fast and how private your own connection is, and getting devices onto Wi-Fi.
- Speed TestDownload, upload, latency and latency under load, with a low-data option.
- IPv4 / IPv6 TestDoes your connection have IPv4, IPv6 or both? Tested separately, not guessed.
- WebRTC Leak TestCheck whether WebRTC exposes a different IP than your VPN shows.
- Wi-Fi QR CodeA QR code that joins a Wi-Fi network when scanned.Runs entirely in your browser — nothing is sent anywhere
- Network ReportMeasure HTTP latency and build a report for IT support, with optional IP masking.
IP lookup
Who an address belongs to, where it is, what network announces it and which cloud runs it.
- IP LookupIdentify any IPv4 or IPv6 address: type, owner, network and ASN.
- Cloud IP CheckWhich cloud, region and service an address belongs to. One address or a whole log.Runs entirely in your browser — nothing is sent anywhere
- RDAP LookupQuery official registries for a domain, IP block or AS number.
- Reverse DNSFind the PTR record an address points back to.
- MAC AddressTell real, randomised, multicast and VM addresses apart; convert formats.Runs entirely in your browser — nothing is sent anywhere
DNS & domains
What a domain publishes, whether every resolver agrees yet, and whether its certificate is sound.
- DNS LookupRead a domain’s A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records.
- DNS PropagationCompare four public resolvers to see whose cache still holds the old answer.
- Domain HealthNameservers, DNSSEC, web, mail, CAA and SOA in one report.
- SSL CertificateExpiry, issuer, names, chain and TLS version of a site’s certificate.
The records that decide whether mail is believed, and reading a message’s own headers.
- Email RecordsCheck a domain's SPF, DKIM and DMARC records and what they actually allow.
- SPF & DMARC GeneratorBuild SPF and DMARC records from choices, ready to paste into DNS.Runs entirely in your browser — nothing is sent anywhere
- Email HeadersTrace a message’s route and delays, and read its authentication verdict.Runs entirely in your browser — nothing is sent anywhere
Subnets & addressing
Subnet masks, CIDR blocks, IPv6 prefixes and address plans, worked out in your browser.
- Subnet CalculatorWork out network, broadcast, usable range, masks and binary form.Runs entirely in your browser — nothing is sent anywhere
- CIDR CalculatorExpand a CIDR block, or check whether an address is inside one.Runs entirely in your browser — nothing is sent anywhere
- Subnet PlannerSplit a network by host count (VLSM), convert ranges to CIDR, merge blocks.Runs entirely in your browser — nothing is sent anywhere
- IPv6 CalculatorExpand, compress and subnet an IPv6 address, and spot a hardware-derived one.Runs entirely in your browser — nothing is sent anywhere
- IP Notation ConverterIPv4 as integer, hex, binary, IPv4-mapped IPv6, NAT64, 6to4 and in-addr.arpa.Runs entirely in your browser — nothing is sent anywhere
- Wildcard MaskSubnet mask ↔ wildcard mask, with ACL and OSPF lines and a match test.Runs entirely in your browser — nothing is sent anywhere
Diagnostics & planning
Reading command output, the commands worth running, and the arithmetic of speed and uptime.
- Ping & Traceroute ReaderPaste ping or traceroute output; find where delay and loss begin.Runs entirely in your browser — nothing is sent anywhere
- Local ChecksThe commands to answer, on your own machine, what a browser cannot.Runs entirely in your browser — nothing is sent anywhere
- Download TimeHow long a transfer takes at a given speed; Mbps ↔ MB/s.Runs entirely in your browser — nothing is sent anywhere
- Uptime CalculatorWhat 99.9 % allows in downtime; combine components in series or parallel.Runs entirely in your browser — nothing is sent anywhere
Security & cryptography
Hashes, HMACs, encryption, password hashing, keys and tokens — all computed in your browser.
- Hash GeneratorMD5, SHA-1/2/3, BLAKE3 and more, for text and files; verify a checksum.Runs entirely in your browser — nothing is sent anywhere
- HMAC GeneratorHMAC-SHA256/512 and more; check webhook signatures.Runs entirely in your browser — nothing is sent anywhere
- Encrypt / DecryptAES-256-GCM with a password, or AES/ChaCha20 with a raw key.Runs entirely in your browser — nothing is sent anywhere
- Password Hashingbcrypt, Argon2id, scrypt and PBKDF2: create and verify hashes.Runs entirely in your browser — nothing is sent anywhere
- Key Pair GeneratorEd25519, ECDSA and RSA keys as PEM, JWK and OpenSSH.Runs entirely in your browser — nothing is sent anywhere
- Password GeneratorPasswords, passphrases, UUIDs and random keys, with entropy shown.Runs entirely in your browser — nothing is sent anywhere
- JWT DecoderDecode a JWT, read its expiry, and verify its signature.Runs entirely in your browser — nothing is sent anywhere
Developer utilities
Everyday conversions and checks for people who work with systems: encodings, JSON, time, schedules.
- JSON FormatterFormat, minify and validate JSON, with the exact line and column of errors.Runs entirely in your browser — nothing is sent anywhere
- Encoder / DecoderBase64, URL, hex, HTML entities, \u escapes and Punycode, both ways.Runs entirely in your browser — nothing is sent anywhere
- Text DiffCompare two texts line by line, with changed words highlighted and a patch.Runs entirely in your browser — nothing is sent anywhere
- Cron ExplainerCron schedules in plain words, with the next run times in any time zone.Runs entirely in your browser — nothing is sent anywhere
- Timestamp ConverterUnix time ↔ readable dates, in several time zones at once.Runs entirely in your browser — nothing is sent anywhere
What is deliberately not here
A tool that produces a confident-looking number it cannot actually measure is worse than no tool. These are left out on purpose:
- Download and upload speed tests. Meaningful throughput testing needs infrastructure this service does not have. The Network Report measures HTTP latency only, and says so.
- Port scanners. Scanning arbitrary hosts on request is a liability and an abuse vector.
- VPN, proxy and Tor detection. These produce probabilities. Presenting a guess as a verdict misleads people.
- Browser fingerprint uniqueness scores. Computing one means building the fingerprint. MyIPKit does not.
- Local network scanning. A browser cannot do it, and a site that tried would be scanning the networks of visitors who never agreed to it. The local checks page gives you the commands instead.
Several of these may arrive later, built properly and labelled honestly. See the roadmap in the project README.
