Check-Host.net Alternative: Multi-Region HTTP Check
Looking for check-host.net? The tool above checks your URL over HTTP from three places at once: Moscow (our own server), Germany and US East, and splits the Moscow timing into DNS, connect, TLS and time to first byte. The two remote measurements come from check-host.net's nodes through its public API, so for those regions you are seeing check-host results with a side-by-side summary.
Three regions is a deliberate, small set. If you need ping, TCP, UDP or DNS checks from dozens of countries, check-host.net itself is the better tool; the section on where it wins says when.
Enterno.io vs Check-Host.net
| Feature | Enterno.io | Check-Host.net |
|---|---|---|
| Price | Free on the site · paid plans from $5/mo | Free |
| Free plan | Yes, no sign-up; per-minute rate limit | Free; API needs no key or registration |
| API | Not for this tool; monitors via REST API v4 with a key | Free JSON API: ping, http, tcp, dns, udp checks |
| Locations | 3: Moscow, Germany, US East (last two via check-host) | 55 nodes in 33 countries (node list, 2026-10-20) |
| Check types | HTTP(S) here; ping, traceroute, DNS on other pages | Ping, HTTP, TCP port, UDP port, DNS, IP info |
| Timing detail | DNS, connect, TLS, TTFB split for the Moscow probe | Total response time per node |
| Scheduled monitoring | Yes, after sign-up, with email/Telegram/Slack/webhook alerts | Not published |

How the three-region check works
- Moscow. Our server requests the URL directly, following up to five redirects with certificate verification on, and records DNS lookup, TCP connect, TLS handshake, time to first byte and total time.
- Germany and US East. The same URL is sent to check-host.net's HTTP check; each node returns a status code and a total response time.
- Verdict per region. The results are compared so a pattern like "fine in Moscow, failing in US East" is stated outright instead of left in three numbers.
- Network owner. The resolved IP is matched to its ASN, so you can see whether the site sits on a known cloud provider.
The detailed DNS/connect/TLS/TTFB split exists only for the Moscow probe, because check-host's HTTP check reports one total time per node.
Where Check-Host is better
- Many more locations. Its public node list had 55 nodes in 33 countries on 20 October 2026, from Brazil and Japan to Iran and Kazakhstan. We cover three regions.
- More check types. Ping, HTTP, TCP port, UDP port and DNS (A, AAAA and PTR with TTL) from those nodes, plus IP geolocation from several databases.
- A free API with no key. Start a check with
/check-http?host=...&max_nodes=..., then read/check-result/<id>. It supports ping, http, tcp, dns and udp. - Shareable reports. Every check gets a permanent report link.
- Extras such as a subnet calculator and a live server terminal.
If your question is "is my site reachable from Singapore, Turkey and Brazil right now", go to check-host.net directly.
When three regions are enough
Many incidents only need three vantage points:
- Geo-blocking and CDN problems. A site that answers in Moscow but times out from Germany and the US, or the reverse, is usually a firewall, a sanctions-related block or a misconfigured CDN edge.
- Slow TLS or DNS. The Moscow breakdown shows whether time goes to DNS, the handshake or the application.
- Continuous checks. A one-off test cannot catch an outage at 3 a.m. Monitors after sign-up run on schedule and alert by email, Telegram, Slack or webhook. The Scout plan checks from Moscow every 5 minutes; plans from Navigator can add more regions.
Reading the timing breakdown
The Moscow probe splits one request into stages, each measured from the start:
- DNS: resolving the hostname. Values above a few hundred milliseconds usually mean a slow or distant authoritative server, or a long CNAME chain.
- Connect: the TCP handshake. It tracks network distance to the server or CDN edge.
- TLS: the handshake on top of TCP. A large gap between connect and TLS points at certificate chain size, OCSP or a slow TLS terminator.
- TTFB: time until the first byte of the response. What remains after TLS is your application and its backend.
If Moscow is fast but the two remote totals are slow, the problem is on the path to those regions; if all three are slow, start with the server.

How Do Ping and Port Scanning Work?
Ping sends ICMP packets to a host and measures response time. Port scanning checks which TCP ports are open and accepting connections — helping diagnose serviceavailability issues.
Configurable Ping
Choose packet count (3, 4, 6, 10). Stats: min/avg/max latency and packet loss.
Common Port Scanner
Check 14 key ports: HTTP, HTTPS, SSH, FTP, SMTP, MySQL, PostgreSQL, and more.
Cloud-Based Check

Frequently Asked Questions
Does Enterno use check-host.net?
Yes. On this page the Germany and US East measurements come from check-host.net nodes via its public API. The Moscow measurement comes from our own server, which is why only Moscow has a DNS, connect, TLS and TTFB breakdown.
How many locations does check-host.net have?
Its public node list showed 55 nodes in 33 countries on 20 October 2026. The list changes as sponsors add or remove servers, so check check-host.net/nodes/hosts for the current set.
Does check-host.net have an API?
Yes, and it needs no key. You start a ping, http, tcp, dns or udp check with an HTTP request and fetch results by request ID. Its API page lists third-party client libraries for several languages.
Can I monitor a site from several regions continuously?
Yes, after sign-up. Monitors alert by email, Telegram, Slack or webhook. The free plan checks from Moscow; plans from Navigator ($19/mo) can add other regions. See the pricing page for limits.
Why do my results differ between regions?
Distance, routing, CDN edges and geo-blocking all change what each region sees. A large gap in one region with normal results elsewhere usually points to the network path or a block, not the application.
