What is a ping test? Measure latency and packet loss online
A ping test checks whether a server or IP address is reachable over the internet and how long data takes to travel there and back (latency). The online ping tool in Netdirekt Looking Glass sends 8 ICMP packets to the target from our AS43391 backbone in Izmir, Turkey; you get the minimum, average and maximum latency, the jitter and the packet loss rate.
What is a ping test used for?
- Checking whether a website, game server or VPS is up and reachable
- Measuring latency from Turkey (Izmir) to the target in milliseconds (ms)
- Seeing whether packets are being lost; a first diagnosis for slowness and dropouts
- Testing IPv4 and IPv6 connectivity separately
How to read a ping result
Latency of about 5–20 ms is normal for targets inside Turkey, 30–70 ms for Europe and 120 ms or more for the Americas. 0% packet loss means a healthy connection; if loss is persistent, run an MTR test to find where it starts. No reply does not always mean an outage: many servers do not answer ping (ICMP) for security reasons.

What is an MTR test? Analyse packet loss and latency hop by hop
MTR (My Traceroute) combines traceroute and ping in one tool: it probes every router (hop) on the path to the target again and again, and measures packet loss and latency for each hop. Our online MTR tool runs 10 rounds, shows the networks crossed with their AS number and operator name, and draws the route on a world map.
What is an MTR test used for?
- Finding which operator and which hop slowness or packet loss starts at
- Providing MTR output as evidence when reporting a problem to your ISP or hosting provider
- Testing the path to a specific port (e.g. 443, 25, 3389) over TCP or UDP when ICMP is blocked
- Seeing where latency increases on the latency profile chart
How to read an MTR result
Loss that appears only at an intermediate hop and does not carry on to later hops is usually harmless; routers give low priority to probe packets addressed to themselves. If loss starts at a hop and continues all the way to the target, that is where the real problem is. When probing over TCP/UDP, a silent target usually means the port is closed or firewalled.

What is traceroute? See your data route with an online tracert
Traceroute (tracert on Windows) lists, in order, the routers your data passes through until it reaches the target. Each hop shows its IP address, reverse DNS name, AS number, country and latency. Our online traceroute runs from Netdirekt's backbone in Izmir for up to 30 hops and shows the route on a map.
What is traceroute used for?
- Seeing which countries and operators your traffic passes through
- Checking whether a route from Turkey leaves the country unnecessarily
- Detecting routing loops and the point where a route breaks
- Comparing the tracert result from your own computer with one taken from another network
What is the difference between traceroute and MTR?
Traceroute sends a few probes to each hop and takes a snapshot of the route. MTR measures the same path many times and produces loss and latency statistics. Use traceroute to see the route and MTR to prove a quality problem. Hops shown as * * * are routers that forward traffic but do not answer probes; on their own they are not a sign of failure.

BGP lookup: which AS path leads to an IP address?
BGP (Border Gateway Protocol) is the routing protocol that decides which IP blocks the networks (autonomous systems) of the internet announce to each other. A BGP route lookup shows the announcement covering the IP address or prefix you enter, the origin AS that announces it, and the AS path from Netdirekt (AS43391) to the target. The data comes from the live, full BGP table of our core routers.
What is a BGP lookup used for?
- Finding out which operator or company announces an IP block (origin AS)
- Seeing which transit provider the traffic leaves through, and the alternative paths
- Checking whether a prefix you just announced has propagated across the internet
- Investigating suspected BGP hijacks, wrong announcements or route leaks
How to read a BGP result
The path marked SELECTED is the best path the traffic uses right now; the alternatives are backup paths. The AS path reads from left to right, from us to the target, and the rightmost AS is the origin network announcing the prefix. The links below the result let you check the same prefix in external BGP sources.

DNS lookup: check A, AAAA, MX, TXT, NS and other DNS records
DNS (Domain Name System) is the internet's directory that translates domain names into IP addresses and service information. Our online DNS lookup instantly shows a domain's A (IPv4), AAAA (IPv6), MX (email), TXT (SPF, DKIM, DMARC, verification), NS (name server), SOA, CNAME, CAA, SRV, DS and DNSKEY records.
What is a DNS lookup used for?
- Checking which IP address a domain points to
- Seeing whether new records have propagated after a hosting or DNS change (DNS propagation)
- Verifying MX, SPF, DKIM and DMARC records when email is not being delivered
- Checking TXT verification records required by services such as Google or Microsoft
- Inspecting DS and DNSKEY records for DNSSEC
How to read a DNS result
NOERROR means the query succeeded, NXDOMAIN means the domain or record does not exist, and SERVFAIL means the name server failed. The TTL tells how many seconds the record is kept in caches; a change you make can take up to that long to be visible everywhere. Use the Recursive DNS test to check the security of your own DNS server.

Recursive DNS test: is your DNS server an open resolver?
A recursive DNS server resolves the names it is asked about by going out to the other name servers on the internet. This service should be available only to your own users. A recursive DNS server left open to everyone is called an open resolver, a common vulnerability abused in DNS amplification DDoS attacks. Our Recursive DNS test sends a real DNS query to the IP address you enter from outside your network and checks whether the server resolves it.
What is the Recursive DNS test used for?
- Finding out whether your server, modem or router offers DNS service to the whole internet
- Verifying “open resolver” notices from your CERT, data center or hosting provider, and re-testing after the fix
- Measuring how many times an open server amplifies a query (amplification factor)
- Checking whether the DNS server reveals its software version to outsiders (version.bind)
How to read a Recursive DNS result
OPEN means the server resolves recursive queries for anyone and must be fixed: use allow-recursion in BIND, Disable recursion in Windows DNS, allow-remote-requests=no on MikroTik, or restrict port 53/UDP to your own network with a firewall. CLOSED means the setup is correct and NO DNS means there is no DNS service at the address. Public DNS services such as 8.8.8.8 and 1.1.1.1 are open on purpose.

Whois lookup: ownership of IP addresses, domains and AS numbers
Whois is a registration lookup that shows who an IP block, a domain name or an autonomous system number (ASN) is registered to. Our whois tool fetches data for IP addresses and AS numbers from regional internet registries such as RIPE NCC, ARIN and APNIC, and for domains from the relevant registry. .tr domains are looked up via TRABIS.
What is a whois lookup used for?
- Finding out which company, country and IP block an IP address belongs to
- Finding the right contact address for abuse reports
- Seeing a domain's registration and expiry dates, registrar and name servers
- Checking which organisation an AS number belongs to (ASN lookup)
How to read a whois result
In IP whois records the inetnum or NetRange line gives the block's range, the org and descr fields its owner, and the abuse-mailbox or OrgAbuseEmail field the complaint address. Owner details of personal domain registrations may be hidden because of GDPR and similar privacy laws.

Internet speed test: measure your download and upload speed to our Izmir server
The speed test measures your connection's download and upload speed and latency against Netdirekt's backbone in Izmir, Turkey. It runs in your browser, with nothing to install. Download is measured with 6 and upload with 4 parallel streams, so the result is realistic on fast fibre connections too.
What is the speed test used for?
- Measuring your home or office internet speed against a server in Turkey
- Checking whether you actually get the speed promised by your subscription
- Seeing the difference between Wi-Fi and a wired connection
- Testing access speed to your server or service at Netdirekt
How to read a speed test result
A browser-based measurement also reflects the limits of your device, your Wi-Fi and your browser. For the most accurate result, connect your computer with a cable, stop background downloads and repeat the test a few times. Latency matters most for gaming and video calls, download and upload speed for file transfers and live streaming.
