Look up A, AAAA, MX, TXT, NS and other DNS records from many countries at once and check whether DNS changes have propagated worldwide.
Resolve a domain from servers in many countries and compare the answers. After changing DNS records, this shows which regions already see the new values and which still have the old ones cached.
check-host.one lets you check a host from many places at once. Enter a domain, IP address or URL and the check runs on servers around the world, so you can see whether a website or server is down for everyone or just for you, and how fast it answers from each region.
Ping a host over ICMP from several countries and compare round-trip time and packet loss per location.
Check whether a port such as 443, 22 or 25565 is open and reachable, even where ICMP ping is blocked.
Check if a website is up: see the HTTP status code and response time from every server.
Trace the network path to a host hop by hop, and compare DNS answers between regions to check propagation.
Checking a host means testing whether a server, website or IP address is reachable and responding. A check from your own computer only shows your connection; checking from many locations shows whether the problem is the host itself or a single network or region.
Yes. Every check is free and needs no account, and each result gets a permanent link you can share.
Yes. Pick countries or whole continents in the server list and use up to 25 servers per check.
