Address-based Tests
Show details for
these testsNAT detection: NAT Detected
Your global IP address is 98.248.46.159 while your local one is 192.168.1.50. You are behind a NAT. Your local address is in unroutable address space.
Your machine numbers TCP source ports sequentially. The following graph shows connection attempts on the X-axis and their corresponding source ports used by your computer on the Y-axis.
DNS-based host information: OK
You are not a Tor exit node for HTTP traffic.
You are listed on the
Spamhaus
Policy Based Blacklist,
meaning that your provider has designated your address block as
one that should only be sending authenticated email, email through the ISP's
mail server, or using webmail.
The
SORBS DUHL
believes you are using a statically assigned IP address.
Reachability Tests
Basic UDP access is available.
Direct UDP access to remote DNS servers (port 53) is allowed.
The applet was also able to directly request a large (~1800B) DNS response.

This is probably for security reasons, as this protocol is generally not designed for use outside the local network.

Direct TCP access to remote NetBIOS servers (port
139) is blocked.

Network Access Link Properties
Network latency measurements: Latency: 81ms Loss: 0.0%
The round-trip time (RTT) between your computer and
our server is 81 msec, which is good.
We recorded no packet loss between your system and our server.
TCP connection setup latency: 91ms
The time it takes your computer to set up a TCP
connection with our server is 91 msec, which is good.
Network background health measurement: Not Executed
The test was not executed. Required functionality was unavailable or not permitted.
Network bandwidth measurements: Upload 11 Mbit/sec, Download >20 Mbit/sec
Your Uplink: We measured your uplink's sending bandwidth
at 11 Mbit/sec. This level of bandwidth works well for many users.
Your Downlink: We measured your downlink's receiving bandwidth
at >20 Mbit/sec. This level of bandwidth works well for many users.
Network buffer measurements: Uplink 180 ms, Downlink is good
We estimate your uplink as having 180 msec of buffering.
This level may serve well for maximizing speed while minimizing the
impact of large transfers on other traffic.
We were not able to produce enough traffic to
load the downlink buffer, or the downlink buffer is particularly small. You probably
have excellent behavior when downloading files and attempting to do other tasks.
HTTP Tests
Address-based HTTP proxy detection: OK
There is no explicit sign of HTTP proxy use based on IP address.
Header-based HTTP proxy detection: OK
No HTTP header or content changes hint at the presence of a proxy.
HTTP proxy detection via malformed requests: OK
Deliberately malformed HTTP requests arrive at our server
unchanged. We are not able to detect a proxy along the path to our
server using this method.
We did not detect file-content filtering.
There is no suggestion that a transparent HTTP cache exists in your network.
The applet was not run from within a frame.
Your web browser reports the following cookies for our web page:
- netAlizEd (set by our server)
Your web browser was unable to fetch an image using IPv6.
DNS Tests
Restricted domain DNS lookup: Failed
Restricted DNS lookup test failed to complete.
Unrestricted domain DNS lookup: Failed
Unable to lookup a name not associated with our server.
The IP address of your ISP's DNS Resolver is 98.248.46.159, which resolves to c-98-248-46-159.hsd1.ca.comcast.net.
DNS resolver properties: Lookup latency: 15ms
Your ISP's DNS resolver requires 15 msec to conduct an external lookup, and 1 msec to lookup an item in the cache.
Your resolver is using QTYPE=A for default queries.
Your resolver is not automatically performing IPv6 queries.
Your DNS resolver requests DNSSEC records.
Your DNS resolver will accept DNS packets of up to 4096 bytes.
Your DNS resolver can successfully receive a
large (>1500 byte) DNS response.
Your resolver does not use 0x20 randomization, but will pass names in a case-sensitive manner.
Your ISP's DNS resolver respects a TTL of 0 seconds.
Your ISP's DNS resolver respects a TTL of 1 seconds.
DNS glue policy: OK
Your ISP's DNS resolver does not accept generic additional (glue) records — good.
Your ISP's DNS resolver accepts additional (glue) records for
nameservers located in subdomains of the queried domain.
Your ISP's DNS resolver does not follow CNAMEs.
DNS resolver port randomization: OK
Your ISP's DNS resolver properly randomizes its local port number.
The following graph shows DNS requests on the x-axis and the detected source ports on the y-axis.
The following graph shows DNS requests on the x-axis and the detected source ports on the y-axis.
DNS lookups of popular domains: OK
74 of 74 popular names were resolved successfully.
In the following table reverse lookups that failed but for which a
Start Of Authority (SOA) entry indicated correct name associations are
shown using an "X", followed by the SOA entry. Absence of both IP
address and reverse name indicates failed forward lookups.
4 popular names have a mild anomaly. The ownership suggested
by the reverse name lookup does not match our understanding of the
original name. The most likely cause is the site's use of a Content
Delivery Network.
| Name | IP Address | Reverse Name/SOA |
|---|---|---|
| www.f-secure.com | 77.67.91.98 | X (ns-pri.ripe.net) |
| www.irs.gov | 77.67.91.122 | X (ns-pri.ripe.net) |
| www.postbank.de | 195.50.155.73 | X (ns1.arcor-ip.de) |
| www.visa.com | 77.67.91.112 | X (ns-pri.ripe.net) |
Your ISP correctly leaves non-resolving names untouched.
