DNS Lookup

DNS results will appear here.

How to read it: A records point to IPv4, AAAA records point to IPv6, MX records route mail, and TXT records often contain verification or email security data.

Ping

Ping status will appear here.

How to read it: Ping checks network reachability and latency. No reply does not always mean a website is down because many hosts block ICMP.

Port Check

Port status will appear here.

How to read it: Open means this server could connect. Closed or timed out can mean firewall rules, a stopped service, provider filtering, or a service bound to another address.

HTTP Headers

HTTP headers will appear here.

How to read it: 301 and 302 are redirects, Cache-Control affects browser and CDN caching, and security headers can change how browsers load the page.

CheckIP Space is more than a number on the screen. These guides explain what each result means, why it matters, and how to use the tools when troubleshooting websites, routers, VPNs, hosting, firewalls, and browser issues.

What is a public IP address?

A public IP address identifies your internet connection when websites, apps, and online services communicate with your device or network. It is usually assigned by your internet service provider and can change depending on your network, router, mobile carrier, VPN, or hosting provider.

What can you learn from IP location, ISP and ASN?

IP location shows the approximate country, region, city and time zone associated with your public address. ISP tells you which network provider announces the connection, while ASN identifies the autonomous system responsible for routing the address on the internet. This is useful when checking whether a VPN is active, confirming a server region, diagnosing routing problems, or understanding why a website may show region-specific content.

Why is IP location approximate?

IP geolocation is based on network ownership and routing databases. It can often estimate the country, region, or city, but it is not the same as GPS and should not be treated as an exact physical address.

IPv4 and IPv6

IPv4 is the classic address format used by most networks. IPv6 is newer and supports a much larger address space. Some internet connections support both, while others expose only one address family.

DNS lookup

DNS lookup helps you see how a domain name resolves. A records point to IPv4 addresses, AAAA records point to IPv6 addresses, MX records show mail servers, NS records show authoritative name servers, and TXT records often contain verification or email security data. When a website, email service, or domain is not working, DNS records are usually the first place to check.

Ping test

Ping is a quick way to test whether a host responds from this server. It can show packet loss, latency, and basic reachability. Some networks block ping, so a failed ping does not always mean the website is down, but it is still helpful for spotting routing issues, unreachable hosts, or unstable network paths.

Port check

Port checking tests whether a service appears open on a target host. For example, web servers commonly listen on ports 80 and 443, SSH often uses 22, and mail services use ports such as 25, 465, 587, 993 or 995. If a port is closed or times out, the cause may be a firewall, service configuration, hosting rule, or provider restriction.

HTTP header check

HTTP headers reveal how a server responds before the page content loads. Status codes, redirects, cache rules, content type, security headers, cookies and server hints can all help diagnose website problems. Header checks are especially useful when testing HTTPS redirects, CDN behavior, cache settings, and security configuration.

Browser information

Browser information shows what your device reports to websites, including user agent, language, screen size, platform, cookie support and connection hints. These details can affect login behavior, layout, localization, analytics, fraud checks, and compatibility testing across desktop and mobile devices.
