55dd.com describes itself as "Oferece uma variedade de maneiras de jogar, junte-se a nós e torne-se o próximo milionário.". It was registered in 2005, served from Toronto, Canada. It has a valid HTTPS certificate, 0 of 6 common security headers.
Does 55dd.com publish the usual trust pages?
None of about, contact, privacy or terms could be found at their usual addresses.
That is common for small or single-purpose sites, and it is also what a disposable
site looks like, so it is worth noting rather than concluding from.
These were checked at conventional paths only, so a site using different URLs may
publish them elsewhere.

Where is 55dd.com hosted?
The first address resolves to infrastructure in Toronto, Canada.
The network is operated by Cloudflare, Inc. (AS13335 Cloudflare, Inc.).

What is 55dd.com running on?
55dd.com exposes 1 identifiable technology: Cloudflare.
Cloudflare sits in front of the origin, so the server header, IP addresses and response timing describe the edge rather than the machine actually running the site.

How does the homepage respond?
The server answered with HTTP 200 over
HTTPS.
At 825ms to first byte this response is slow for a homepage measured from a single European location.
The HTML weighs 32KB, which is ordinary for a homepage.
The HTML is compressed with gzip.
| Server header | cloudflare |
|---|---|
| Compression | gzip |
| Page size | 33,078 bytes |
| Declared language | en |
| Mobile viewport | declared |
What does the homepage say about itself?
The homepage has no title element at all, which leaves search engines to invent one from the page content.
A meta description of 91 characters is present.
No H1 heading was found, so the page offers no single top-level statement of what it is.
| Title | — none — (0 chars) |
|---|---|
| Meta description | Oferece uma variedade de maneiras de jogar, junte-se a nós e torne-se o próximo milionário. (91 chars) |
| H1 | — none — (0 on the page) |
| Canonical | not set |
| Open Graph title | 55dd |

Is 55dd.com served over a valid certificate?
The HTTPS certificate is issued by Google Trust Services and is
valid until 2027-01-01, which is 88 days from the date of this check. It covers
1 hostname.
- 55dd.com
The certificate has 88 days left to run.
It covers 1 hostname, so it was issued for this site specifically.
Which security headers does it set?
None of the 6 headers checked are set. That is the default state of most servers rather than evidence of a problem, but it means the browser is given no instructions it could otherwise act on.
Without HSTS, a browser that has never visited before will try HTTP first, which is the window a network attacker needs.
With no Content Security Policy, any script that reaches the page — including one injected through a compromised third-party dependency — runs with full access to it.
| Header | Set | Value |
|---|---|---|
| HSTS | no | — |
| Content Security Policy | no | — |
| X-Content-Type-Options | no | — |
| X-Frame-Options | no | — |
| Referrer-Policy | no | — |
| Permissions-Policy | no | — |
How is DNS configured for 55dd.com?
| IP addresses | 172.64.144.154, 104.18.43.102, 2a06:98c1:310d::ac40:909a, 2a06:98c1:3109::6812:2b66 |
|---|---|
| Reverse DNS | 172.64.144.154, 104.18.43.102 |
| Name servers | — |
| Mail (MX) | no mail records |
| SPF | not published |
| TXT records | 0 |
55dd.com resolves to 4 addresses, which indicates load balancing or a CDN rather than a single origin server.
No MX records are published, so this domain does not receive mail at its apex. Mail sent to it will bounce.
No SPF record is published. Receiving servers therefore have no published rule for who may send mail as this domain, which makes spoofing it materially easier.
Reverse DNS resolves to 172.64.144.154, 104.18.43.102, which usually names the hosting provider.
Who runs DNS and mail for 55dd.com?
The domain publishes AAAA records and accepts connections over IPv6.
What else is worth noting about 55dd.com?
3 of 3 externally hosted scripts carry no subresource integrity hash. If one of those hosts were compromised, the replacement script would run with full access to the page.
Can 55dd.com be spoofed in email?
No DMARC record is published, so there is no instruction telling receiving servers what to do with mail that fails authentication. In practice that means forged mail from this domain is likely to be delivered.
CAA records restrict certificate issuance to 1 named authority (tiaozhuan-7889963.9-p-a-x.com.), so no other CA should be able to issue for this domain.
The zone is DNSSEC-signed, so resolvers can verify the DNS answers have not been tampered with in transit.
What does robots.txt allow?
No robots.txt was served. Crawlers treat a missing file as permission to crawl
everything, so this is an open crawl policy by default rather than a blocked one.
What structured data does the homepage publish?
No JSON-LD or microdata was found on the homepage.
What does 55dd.com load from third parties?
The homepage pulls resources from 6 third-party hosts (challenges.cloudflare.com, fonts.googleapis.com, fonts.gstatic.com, o.alicdn.com, telegram.org, upload-us.f-1-g-h.com). Each one sees the visitor IP and user agent on every page load.
1 cookie is set before any interaction (__cf_bm).
| Cookie | Secure | HttpOnly | SameSite |
|---|---|---|---|
| __cf_bm | yes | yes | none |
Does 55dd.com settle on one address?
Plain HTTP redirects to HTTPS, so visitors who type the bare address still land on the secure version.
The www address redirects to https://55dd1.com/?_ts=%3D%3DgMyUCN5cTN1IDOzETM5cTMyITJ, so the site settles on one canonical hostname.
How easily can 55dd.com be crawled?
No readable sitemap was found, so crawlers have to discover every page by following links.
A deliberately invalid URL correctly returns HTTP 404, so missing pages will not be indexed.
What tracking does 55dd.com run?
No analytics or advertising trackers were detected on the homepage of 55dd.com, which is unusual for a commercial site.
How does 55dd.com look when shared?
All five social preview tags are present, so links shared to social platforms and chat apps will render with a title, description and image.
How are images, fonts and scripts handled?
Fonts are loaded from Google Fonts, which means every page view also contacts Google. Self-hosting removes that dependency.
The page pulls 2 external stylesheets and 6 external scripts, with 3 carrying defer or async.
Responses carry Cloudflare edge headers, so content is served from a CDN rather than straight from the origin.
Is 55dd.com accessible and current?
The page uses 0 landmark elements and 0 ARIA attributes.
No skip-to-content link was found, which keyboard users rely on to bypass navigation.
Can search engines index 55dd.com?
Nothing on the homepage prevents indexing: no noindex is set in the robots meta tag or the X-Robots-Tag header.
No canonical URL is declared, which leaves duplicate addresses of this page to be resolved by the search engine.
Visible text is only 0% of the HTML, which indicates the page is assembled in the browser rather than served as content.
How is 55dd.com delivered?
The HTML is served with Cache-Control: no-cache.
HTTP/3 is advertised via alt-svc, so modern browsers will upgrade to QUIC after the first visit.
Frequently asked questions
Does 55dd.com set the usual HTTP security headers?
It sets 0 of 6. The ones not present are: HSTS, Content Security Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy.
Does 55dd.com allow AI crawlers?
No robots.txt is served, so nothing is disallowed and AI crawlers are free to read the site.
What is 55dd.com built with?
The homepage exposes these fingerprints: Cloudflare. A site behind a CDN or rendered server-side may use more than it reveals.
Where does this data come from?
Every figure was measured by our own server on 4 October 2026: DNS lookups, one HTTPS request to the homepage, a TLS handshake and a request for robots.txt. No third-party SEO API is involved.
Is any of this traffic or authority data?
No. Traffic, authority and ranking figures cannot be measured by inspecting a domain, only modelled. Everything here is a direct observation.
I own 55dd.com and want this page removed.
Ask through the contact page on this site, from an address at the domain, and the report will be taken down. It only ever shows what the domain already serves publicly.
