Bulk lookup Apple device manufacturers, models, and production details via MAC address. Ideal for IT management and device verification.
Shows MACLookup address-block registrant records, not proof of a device brand, location or owner. isPrivate means the registrant hides public details; isRand is the service flag. Update dates are service records, not a real-time guarantee. Reference
输入格式说明
每行一个MAC地址，支持多种格式：00:1A:2B:3C:4D:5E、00-1A-2B-3C-4D-5E、001A2B3C4D5E
• 每次最多支持 500 条记录批量查询（会员功能）
• 点击下一步后会自动进行MAC地址格式校验
• 开启去重后，开始查询时将自动移除重复的MAC地址，保留首次出现的记录
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Paste or import a list of MAC addresses or hexadecimal prefixes to look up registration metadata for each valid entry. A match can include the registered organization, address, country or region, matched prefix, block type, and—when supplied—block boundaries, block size, record update date, randomized-address flag, or private-registration flag. These fields describe an address allocation record. They do not establish the exact device model, current owner, physical location, or live network inventory.
OUI is a familiar 24-bit organization identifier, but IEEE assignments also include MA-M and MA-S blocks with more specific prefixes. IEEE describes MA-L, MA-M, and MA-S as allocation sizes for EUI identifiers. A match may therefore use more than the first three bytes. Read the returned prefix and block type together rather than treating every vendor result as a simple first-three-byte lookup.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Paste one entry per line, or upload a spreadsheet or text file. For text, the first space-, comma-, or tab-separated field on each line is used. Spreadsheet input reads the first worksheet, skips its first row as a header, and takes the first column.
A batch accepts up to 500 entries. The file picker accepts spreadsheet formats such as XLS/XLSX and text input such as CSV or TXT. Check the parsed preview for invalid and repeated rows before starting.
Deduplication is on by default and compares addresses after removing separators and normalizing letter case. Turn it off only when repeated source rows need to remain distinct in your work.
Start lookup, monitor found, not-found, and error statuses, and stop or retry as needed. Review registration fields alongside your original asset records. Export the resulting workbook for later reconciliation.
Inputs may use colon-separated, hyphen-separated, or unseparated hex forms. A complete 12-hex-digit MAC is useful for retaining the specific device address; a shorter prefix can still be accepted if it contains at least six hex digits.
Use cases
See how the tool fits into real work and everyday tasks.
An IT team can match a switch export against registered organization names, then use the prefix and existing inventory fields to investigate discrepancies.
An administrator can review a group of newly observed addresses and use registration data as one clue when deciding which records need manual follow-up.
Import rows from a spreadsheet, inspect the preview and statuses, then export lookup results for comparison with the source list.
Q&A
Find concise answers to common questions and confusing cases.
It identifies the organization associated with the matched address block in registration data. It may not identify the finished device brand, model, reseller, or current operator.
The lookup may have no matching registration record, or the address may be locally assigned or randomized. Treat not-found and error statuses separately and confirm the original address was entered correctly.
Yes, but the first worksheet is read, its first row is skipped, and the first column supplies the addresses. Put MAC values in that column and include a header row.
Notes
Review scope, result limitations, and important precautions before use.
Registration records are allocation metadata, not an asset-management database. Locally administered or randomized addresses may not map to a manufacturer record, and a successful match is not proof of device identity. Verify important inventory decisions with device records or network evidence. The lookup returns records available to the service when queried; this content does not promise a particular refresh interval or complete coverage.
