a1.gs

We performed a comprehensive analysis of a1.gs on 2026-06-28. The website returned an HTTP 200 status code with a server response time of 8659ms. The page is served over HTTP/1.1 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 363 KB. Warning: The website does not have a valid SSL certificate. Visitors may see security warnings in their browser, and data transmitted to and from this website is not encrypted. The security headers analysis reveals a score of 0/100 (poor). No security headers are configured, which is a significant security concern. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy, which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 2 technologies across 2 categories powering a1.gs. The detected stack includes React and Google Fonts. The UI is built with React. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, a1.gs receives an overall trust score of 45/100, classified as "Caution Advised".

After conducting a thorough safety and legitimacy analysis, a1.gs receives a trust score of 45/100, which places it in the "Caution Advised" category. This score is calculated by evaluating multiple factors including SSL certificate validity, domain registration history, email authentication protocols, security header configuration, and blacklist status across major threat intelligence databases. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), missing Referrer-Policy, potentially leaking URL information to third parties, the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity, and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked a1.gs against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal. The domain passed all 8 checks with a clean status, meaning it has not been flagged for phishing, malware distribution, spam, or other malicious activities by any of the tested threat intelligence providers.

Our technology detection engine scanned a1.gs and identified 2 distinct technologies across 2 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. UI Library: React — handles the user interface rendering and component management for a1.gs. Fonts: Google Fonts — delivers web fonts for typography for a1.gs.

a1.gs resolves to the IPv4 address 186.241.74.109, but does not support IPv6. IPv6 adoption is increasingly important as IPv4 address space becomes exhausted, and some ISPs and regions are transitioning to IPv6-only connectivity. The domain has 1 A record(s) configured. The domain name system is managed by 6 name servers: ns1.myhostadmin.net, ns2.myhostadmin.net, ns3.myhostadmin.net, ns4.myhostadmin.net, ns5.myhostadmin.net, and ns6.myhostadmin.net. Having 6 name servers provides good redundancy — if one fails, the others can continue serving DNS queries. The choice of name servers often indicates the DNS hosting provider or CDN service being used. SPF is not configured, meaning any server could potentially send emails pretending to be from this domain. This is a significant email security concern. DMARC is not configured, leaving the domain vulnerable to email spoofing and phishing attacks that impersonate this domain. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is not enabled for a1.gs. While not critical for most websites, DNSSEC adds an important security layer by ensuring DNS responses haven't been tampered with during transit. Enabling DNSSEC is recommended for domains handling sensitive data or financial transactions. Our subdomain enumeration scan discovered 3 active subdomains for a1.gs: blog.a1.gs, m.a1.gs, and www.a1.gs. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The title tag for a1.gs is good at 22 characters: "邓柠檬工具集 | 1000+免费在线工具大全". The length is acceptable, though it may be slightly truncated in some search result displays. The meta description is 106 characters (well-optimized): "本站是一个纯前端工具集，包含 1086+ 个纯前端开发者工具：JSON 格式化、时间戳转换、Base64 编解码、二维码生成、图片压缩、房贷计算、加密货币工具等。单文件、零构建、可完全离线使用，无广告且保护隐私。". Google typically displays up to 155-160 characters of the meta description in search results. A compelling meta description with a clear call-to-action can significantly improve click-through rates from search results. The canonical url is correctly set to http://dnmb.cn/, preventing duplicate content issues, the page language is declared as zh-cn, the meta robots directive is set to index, follow, and a favicon is configured. Open Graph meta tags are configured with 4/4 recommended fields: OG title ("WebUtils - 纯前端工具集..."), OG description, OG image (social sharing thumbnail), OG type (website). These tags control how the page appears when shared on Facebook, LinkedIn, and other social media platforms that support the Open Graph protocol. A Twitter Card of type summary is configured, which controls how links appear when shared on Twitter/X. The "summary" type displays a large image preview, which typically generates higher engagement rates than the basic card type. The site implements Schema.org structured data with the following types: Answer, FAQPage, Offer, Organization, Person, Question, SearchAction, WebApplication, and WebSite. Structured data helps search engines understand the page content and can enable rich results (featured snippets, knowledge panels, star ratings) in Google search results, which can significantly increase click-through rates. The meta keywords tag contains 8 terms including 前端工具, 开发工具, JSON格式化, 时间戳转换, and Base64. Note: Google has officially confirmed that it does not use the meta keywords tag as a ranking signal. However, some other search engines (Bing, Yandex) may still reference it.
