macaddresslookup.info

What It Is

macaddresslookup.info is a MAC Address Vendor Lookup tool aimed at developers and network operations scenarios. It is used to identify the corresponding vendor from a MAC address. The page provides an online input box, along with CLI curl and PHP examples, as well as a bulk POST API. Its positioning is fairly clear: offering simple vendor-identification capabilities for scripts, backend systems, or operations tools.

Core Features and API

Based on the captured page content, it supports single MAC address lookup: send a GET request to https://macaddresslookup.info/lookup/?mac=... to obtain the result. Bulk lookup uses POST https://macaddresslookup.info/lookup/bulk/, with a JSON request body, for example containing a mac_addresses array. The response is also JSON and includes success, count, and results; each result contains the normalized mac_address, valid, and vendor fields. It also supports multiple common input formats, including hyphen-separated, colon-separated, dot-separated, and delimiter-free formats, reducing the need for input preprocessing.

Languages, Integration, and Documentation

The page only shows curl and PHP examples. It does not mention any official SDKs or support for specific frameworks. Since the API uses standard HTTP/JSON, it can in practice be called from Python, Go, Node.js, Java, and other languages, but that is a general capability rather than something documented with dedicated examples. The documentation is sufficient for quick onboarding: the examples are straightforward, and the request and response structures are clear. However, it is still limited for production integration, as it does not explain error codes, authentication methods, rate limits, database sources, update frequency, API versioning strategy, or service SLA.

Pricing and Deployability

The page does not disclose its pricing model, free quota, paid plans, or payment methods, nor does it state whether an API Key is required. There is also no information on whether it is open source or can be self-hosted. Before adopting it in a commercial system, you should further confirm stability, licensing, rate limits, and data compliance considerations.

Pros, Cons, and Ideal Users

Its strengths are that it is lightweight, easy to call, supports bulk queries, and returns structured responses. It is suitable for network asset inventory, security log analysis, device identification, and internal operations scripts. The drawbacks are limited disclosure, lack of complete developer documentation, and no clear service guarantee. It may not be ideal for core production workflows with high requirements for accuracy, availability, and compliance unless further validated.

Access from China and Alternatives

Access conditions from mainland China are not mentioned in the page content, so actual availability needs to be tested independently; payment methods are also unknown. If access is unstable or more authoritative data is needed, alternatives or backup data sources include the IEEE OUI database, Wireshark OUI data, macvendors.com, or other MAC Vendors APIs.
