MAC Address Converter — Format Normalization Local Text Tool
Normalize MAC address notation locally — colon, hyphen, Cisco dot, or bare hex in your browser
How to Use This Tool
- Paste MAC address strings into the textarea.
- Click Transform for local browser-side processing.
- generic-text handler — no extended API call.
- Document target format: colon, hyphen, dot, or bare.
- Manually verify twelve hex digits after conversion.
- Cross-check OUI with oui-lookup for vendor notes.
About This Tool
Inventory imports, switch ACLs, and DHCP logs use incompatible MAC formats — Cisco AABB.CCDD.EEFF versus Linux AA:BB:CC:DD:EE:FF versus bare AABBCCDDEEFF. VSPIC mac-address-converter maps to type client, kind generic-text per missing-tools-handlers.generated.ts — MissingClientWidgets ToolUiShell with textarea and Transform button processing strings locally in the browser without server upload.
This is a local scratchpad for format normalization notes — not automated IEEE bit validation or OUI lookup. Paste MAC strings, document target format for your CMDB, and apply Transform per generic-text widget behavior. For vendor identification, use oui-lookup scratchpad or mac-address-lookup. mac-address-validator and random-mac-generator currently proxy tor-exit — not conversion.
Common use cases
- •Inspect HTTP headers and user-agent strings
- •Analyze email headers for phishing investigation
- •Generate strong passwords for staging environments
Why use VSPIC for ?
- Browser-only processing — MAC inventory stays local.
- Honest generic-text capability documentation.
- Scratchpad for colon hyphen dot format notes.
- No server transmission of hardware addresses.
- Free — no account required.
- Pairs with MAC validation rules on mac-address-validator page.
generic-text client handler behavior
missing-tools-handlers.generated.ts maps mac-address-converter to type client, kind generic-text. MissingClientWidgets renders Textarea and Transform — local processing only.
We document honestly: capabilities follow generic-text implementation, not a dedicated MAC parser with guaranteed colon-dot conversion.
Common MAC format notations
Colon separated: AA:BB:CC:DD:EE:FF — Linux, Windows getmac, most APIs. Hyphen: AA-BB-CC-DD-EE-FF — some Windows utilities. Cisco dot: AABB.CCDD.EEFF — IOS show interfaces. Bare: AABBCCDDEEFF — databases and QR codes.
Normalize case to uppercase for consistent CMDB matching.
Manual conversion workflow
Strip separators, verify twelve hex digits, reinsert colons every two characters. For Cisco dot, split into 4-4-4 grouping after stripping.
Paste intermediate steps into textarea for audit trail before CMDB import.
Relationship to mac-address-validator page
mac-address-validator SEO page teaches IEEE validation rules but widget proxies tor-exit. This converter scratchpad handles format strings; validator page teaches bit rules for manual checks.
Relationship to oui-lookup
oui-lookup generic-text scratchpad documents vendor research notes from first three octets. Combine: convert format here, identify vendor in oui notes.
Switch ACL and 802.1X formatting
Cisco port-security sticky MAC expects Cisco format. RADIUS attributes may want bare hex. Document per-platform target in textarea before change window.
Privacy MAC randomization notation
Randomized client MACs use LAA range — second hex 2, 6, A, E. Format conversion does not alter bit semantics — only string representation.
Bulk conversion limits
Textarea suits tens of addresses for ticket work. Thousand-row DHCP exports need spreadsheet formulas — SUBSTITUTE and REGEX in Excel or Python script.
Future dedicated MAC converter handler
Dedicated kind mac-converter could guarantee colon hyphen dot bare output with validation. Until handlers batch update, generic-text scratchpad persists.
Check missing-tools-handlers.generated.ts for kind changes.
Important notes & limitations
- Transform scope depends on generic-text widget — may not auto-convert all formats.
- Does not validate unicast multicast or LAA bits.
- No OUI vendor database lookup in this widget.
- Not a substitute for dedicated MAC parser script.
- Bulk thousand-MAC ETL needs offline tooling.
