We have collected here some useful links to help you find out if ZMap is good.
Check the traffic stats of ZMap on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of ZMap on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of ZMap's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of ZMap on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

They already had your IP. The whole internet (IPv4 adress space) can be scanned in less than one hour (see: https://zmap.io. Source: about 3 years ago
The numbers above demonstrate that it is theoretically possible to mass scan the entire internet. Effective free-to-use tools can be used to perform mass scans, converting this academic opportunity into practice. ZMap, Masscan, and others promise to scan the entire public IPv4 address space in some ten minutes or so on a typical desktop computer with a gigabit Ethernet connection. Researchers proved that the time... - Source: dev.to / over 3 years ago

Zmap (zmap.io) is probably the fastest port scanner. But afaik it's main usage is to scan 1 port on the whole internet instead of all ports on one IP (but you can, too). Source: almost 4 years ago

ZMap claims to be able to scan the entire IPv4 space of the Internet in about 45mins. [0] There's no reason not to believe that claim, either. With many people doing this, it is kind of surprising that it took so long for a vulnerable server to be discovered. [0] https://zmap.io/. - Source: Hacker News / over 4 years ago
LOL. There is a company in town here that spun out of the zmap project. https://censys.io/overview https://zmap.io can scan the entire ipv4 address space in 5minutes. Source: over 4 years ago
ZMap has garnered significant attention within the network scanning community due to its unique capabilities and robust feature set, distinguishing itself as a powerful tool primarily for security monitoring and network scanning tasks. Being open-source and developed with the capability to perform Internet-wide scans efficiently, ZMap has gained particular traction among researchers and security professionals who value its speed and scalability.
A notable standout feature of ZMap is its ability to conduct rapid scans across the entire IPv4 address space, making it distinct from other tools such as Nmap. Numerous posts and articles emphasize ZMap's impressive speed, with claims of scanning the entire Internet in approximately 45 minutes to less than an hour depending on network conditions, using a typical desktop computer with gigabit Ethernet. This capability is especially significant for researchers and penetration testers interested in large-scale studies or audits.
ZMap excels at probing single ports across vast arrays of networked devices quickly and efficiently, allowing users to discover open services without comprehensive evaluation of individual devices—a feature that caters well to large-scale operations. This focus on scalability over flexibility challenges traditional tools like Nmap, which are designed for detailed scans across fewer devices.
Additionally, ZMap's ecosystem of supplementary tools, such as ZGrab, ZTag, ZBlacklist, ZAnnotate, and ZCertificate, expand its utility by offering enhancements like application-state scanning, metadata tagging, blacklist management, and certificate parsing. These complementary tools illustrate a well-rounded approach to network analysis, aiming to provide thorough insights into the state and vulnerabilities of networked environments.
General sentiment towards ZMap underscores its efficiency and usefulness for specific applications. The tool performs exceptionally well for mass scans, enabling security audits and research that require comprehensive data but on a larger scale. This has been particularly useful for identifying vulnerable servers and services quickly, as highlighted by posts discussing ZMap's role in identifying publicly exposed services.
However, ZMap's function as a single-port scanner suggests that it may not be the best fit for scenarios demanding detailed per-device analysis across multiple ports, where more flexible tools like Nmap might excel. Nonetheless, its integration in academic and professional circles highlights its value as a research tool.
The ZMap project has also inspired surrounding contributions and innovations, such as Censys, which spins out of the ZMap project, focusing on indexing and querying Internet-wide scan data. This underscores the tool's influence and the significance of the data it can garner when integrated with comprehensive analysis platforms.
Overall, ZMap’s streamlined architecture and its ecosystem demonstrate a focus on speed and scalability, making it an essential tool in security research and network analysis for extensive Internet-wide projects. Its reception within the community is positive, particularly amongst those who require extensive network visibility quickly, though it may not replace more detailed network analysis tools for in-depth security investigations.
