Tests Description

Website Test
The Website test verifies the server status, downloads the full HTML content and measures the response time of the test website. The test results display the times for DNS lookup, connect, download the first byte and download the complete HTML of the tested website.

Web Page Test
The Web page test verifies the URL availability, downloads the complete HTML content, the images and all the other internal web page objects and measures the download speed of each of the components. The test results display DNS time, connect time, first and last byte times for each of the web page objects. This test is limited to the initial 30 page objects.

HTTP Headers test
The HTTP Headers test requests the entered URL, retrieves the HTTP response headers, verifies the HTTP status codes and displays the received response headers. Find out more about the different HTTP status codes

Website Test behind the Great Firewall of China
'Website Test behind the Great Firewall of China' will test whether your web-site is visible from China. The monitoring agent resolves the domain name from selected location in China, connects to the test website and downloads the complete HTML content. The test results display DNS lookup time, time to connect, time to download the first byte and time to download the complete HTML of the tested web site.

HostName Test
The HostName test performs DNS lookup and provides information about how a domain or hostname (www.yourdomain.com) is resolved to an IP address (69.147.114.210). Common use of the HostName test is to verify that the DNS records are correct and specific domain points to the correct IP address.

MX lookup
The MX lookup test performs an MX record (Mail exchanger record) lookup for a specific e-mail address, which returns a list with servers responsible for delivering e-mail to that address and their priority relative to each other. The test results display the hostnames and IP addresses of the Mail Exchange Servers.

NS records lookup
The NS lookup test performs an NS record (Name Servers record) lookup for a specific domain name, which returns the Name Servers responsible for the domain name records. The test results display the hostnames and IP addresses of the Name Servers.

SPF lookup
The SPF (Sender Policy Framework) lookup test does a query for the DNS records and returns any available SPF records for a given domain name. For more information on SPF, check the SPF web site.

Reverse DNS
The Reverse DNS test performs a reverse DNS lookup for a specific IP address and returns the hostname associated with that IP address.

Blacklist Check
The Blacklist check queries the major DNS Blacklists - Sorbs, Spamhaus, NJABL, DSBL, CBL and PSBL for specific IP address and returns whether it is listed for sending spam, as an open proxy relay or for other possibly malicious activities.

Server Test
The Server test verifies the availability and measures the response time of any TCP/UDP based web service connected to the Internet. Server tests include HTTP, HTTPS, FTP, SMTP, POP3, IMAP, SSH, Telnet, DNS and Custom services.

Email Validation test
The Email Validation test validates the syntax of the entered email address, performs a DNS query for the domain and checks all SMTP servers listed in the MX (Mail Exchanger) records.

PING Test
The PING test checks if a web host or IP address is reachable across the Internet by sending multiple ICMP packets and listening for the replies. The PING test measures the time it takes the packets to go from the selected testing monitoring location to the host tested. The test results display the shortest, the average and the maximum round-trip times and packet loss rate between hosts.

Traceroute
The Traceroute test (a.k.a. trace route, tracert) will trace the route that test packets take from one web destination to another. The test results provide a list of hosts or IP addresses showing the route taken by the test packets starting from the selected monitoring location to the destination Domain or IP.

WHOIS
The WHOIS query determines the owner and/or the administrator of a domain name and provides contact details. The WHOIS system originated as a method that system administrators could use to look up information to contact other IP address or domain name administrators, almost like "white pages".

IP / Network Lookup
The IP / Network Lookup does a WHOIS query to determine the owner and/or the administrator of an IP address or network and to provide contact details.

MTR - traceroute & ping
The MTR test is based on the linux program MTR, which combines the functionality of the "traceroute" and "ping" programs in a single network diagnostic tool. See the MTR official page for more info on MTR.
