Into DNS, a free DNS checking service

Status Test name Information
Parent Info Domain NS records Nameserver records returned by the parent servers are: [''] (NO GLUE) [TTL=14400] [''] (NO GLUE) [TTL=14400] was kind enough to give us that information.
Pass TLD Parent Check Good., the parent server I interogated, has information for your TLD. This is a good thing as there are some other domain extensions like "" for example that are missing a direct check.
Pass Your nameservers are listed Good. The parent server has your nameservers listed. This is a must if you want to be found as anyone that does not know your DNS servers will first ask the parent nameservers.
Info DNS Parent sent Glue The parent nameserver is not sending out GLUE for every nameservers listed, meaning he is sending out your nameservers host names without sending the A records of those nameservers. It's ok but you have to know that this will require an extra A lookup that can delay a little the connections to your site. This happends a lot if you have nameservers on different TLD ( for example with nameserver
Pass Nameservers A records Good. Every nameserver listed has A records. This is a must if you want to be found.
NS Info NS records from your nameserversNS records got from your nameservers listed at the parent NS are: [''] [TTL=7200] [''] [TTL=7200]

Error Recursive Queries I could use the nameservers listed below to performe recursive queries. It may be that I am wrong but the chances of that are low. You should not have nameservers that allow recursive queries as this will allow almost anyone to use your nameservers and can cause problems. Problem record(s) are:
Warn Same Glue Looks like the A records (the GLUE) got from the parent zone check are different than the ones got from your nameservers. You have to make sure your parent server has the same NS records for your zone as you do.I detected some problems as follows:
For the parent reported: [''] and your nameservers reported: ['']
For the parent reported: [''] and your nameservers reported: ['']
Pass Glue for NS records OK. When I asked your nameservers for your NS records they also returned the A records for the NS records. This is a good thing as it will spare an extra A lookup needed to find those A records.
Pass Mismatched NS records OK. The NS records at all your nameservers are identical.
Pass DNS servers responded Good. All nameservers listed at the parent server responded.
Pass Name of nameservers are valid OK. All of the NS records that your nameservers report seem valid.
Pass Multiple Nameservers Good. You have multiple nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me.
Pass Nameservers are lame OK. All the nameservers listed at the parent servers answer authoritatively for your domain.
Pass Missing nameservers reported by parent OK. All NS records are the same at the parent and at your nameservers.
Pass Missing nameservers reported by your nameservers OK. All nameservers returned by the parent server are the same as the ones reported by your nameservers.
Pass Domain CNAMEs OK. RFC1912 2.4 and RFC2181 10.3 state that there should be no CNAMEs if an NS (or any other) record is present.
Pass NSs CNAME check OK. RFC1912 2.4 and RFC2181 10.3 state that there should be no CNAMEs if an NS (or any other) record is present.
Pass Different subnets OK. Looks like you have nameservers on different subnets!
Pass IPs of nameservers are public Ok. Looks like the IP addresses of your nameservers are public. This is a good thing because it will prevent DNS delays and other problems like
Pass DNS servers allow TCP connection OK. Seems all your DNS servers allow TCP connections. This is a good thing and usefull even if UDP connections are used by default.
Pass Different autonomous systems OK. It seems you are safe from a single point of failure. You must be carefull about this and try to have nameservers on different locations as it can prevent a lot of problems if one nameserver goes down.
Pass Stealth NS records sent Ok. No stealth ns records are sent
SOA Info SOA recordThe SOA record is:
Primary nameserver:
Hostmaster E-mail address:
Serial #: 1256841781
Refresh: 28800
Retry: 7200
Expire: 2419200 4 weeks
Default TTL: 7200
Pass NSs have same SOA serial OK. All your nameservers agree that your SOA serial number is 1256841781.
Pass SOA MNAME entry OK. That server is listed at the parent servers.
Warn SOA Serial Your SOA serial number is: 1256841781. This can be ok if you know what you are doing.
Pass SOA REFRESH OK. Your SOA REFRESH interval is: 28800. That is OK
Pass SOA RETRY Your SOA RETRY value is: 7200. Looks ok
Pass SOA EXPIRE Your SOA EXPIRE number is: 2419200.Looks ok
Pass SOA MINIMUM TTL Your SOA MINIMUM TTL is: 7200. This value was used to serve as a default TTL for records without a given TTL value and now is used for negative caching (indicates how long a resolver may cache the negative answer). RFC2308 recommands a value of 1-3 hours. Your value of 7200 is OK.
MX Info MX RecordsYour MX records that were reported by your nameservers are:


[These are all the MX records that I found. If there are some non common MX records at your nameservers you should see them below. ]
Pass Different MX records at nameservers Good. Looks like all your nameservers have the same set of MX records. This tests to see if there are any MX records not reported by all your nameservers and also MX records that have the same hostname but different IPs
Pass MX name validity Good. I did not detect any invalid hostnames for your MX records.
Pass MX IPs are public OK. All of your MX records appear to use public IPs.
Pass MX CNAME Check OK. No problems here.
Pass MX A request returns CNAME OK. No CNAMEs returned for A records lookups.
Pass MX is not IP OK. All of your MX records are host names.
Info Number of MX records OK. Looks like you only have one MX record at your nameservers. You should be carefull about what you are doing since you have a single point of failure that can lead to mail being lost if the server is down for a long time.
Pass Mismatched MX A OK. I did not detect differing IPs for your MX records.
Pass Duplicate MX A records OK. I have not found duplicate IP(s) for your MX records. This is a good thing.
Pass Reverse MX A records (PTR) Your reverse (PTR) record: ->
You have reverse (PTR) records for all your IPs, that is a good thing.
WWW Info WWW A Record Your A record is: []
Pass IPs are public OK. All of your WWW IPs appear to be public IPs.

Expired domain auction for Russian domains

Effective November 9 RU-CENTER'S fee for a domain sold at an auction will
reduce down to 7% and now
minimum and maximum fee limits are thereby abolished. This makes the domains
sale process at more profitable!

Furthermore, the users may specify the dedicated rubrics, for which the sold
domain may be attributed to.
This will ease the domain search for the buyers and enhance the chance of
its successful sale.

Rubrics and descriptions of the domains sold may be changed at any auction

With a view to the above, effective November 9, 2009 the "Domain Name
Auction Schedule" will be modified accordingly.

Registering a Slovenian (.si) domain name

When setting up a Slovenian (.si) domain name, you can check the DNS setup with this tool on , the slovenian NIC.

When working correctly, the results should be:


Automatically is being checked:

  • domain name registration
  • number of NS records
  • values in SOA record
  • consistency of SOA and NS records
  • authority of given nameservers
  • activity of email address in SOA record

DNS checking is based on following standards and recommendations:

Lines in report that start with:

  • OK: are messages about successful tests
  • INFO: are informative messages
  • WARN: are messages about potentially problematic settings
  • ERROR: are error messages

ERROR: line is usually followed by a group of INFO: lines that describe possible reasons for errors.

Note: Messages describing errors can be repeated in predelegation process
if checkings are performed in different phases of the process.

If you notice domain name repeatedly in error messages, for example:

INFO: Primary MX record for 10

this means you forgot to put an '.' at the end of the record, which results in default addition of local domain.

Whole procedure and possible error reasons can be found below.

For additional information about domain delegation, please contact your registrar.

- DNS will resolve normally - although operational through this downtime, any changes to DNS settings may be delayed intermittently for a period of up to 24 hours from the start of the maintenance period
- All web hosting services will work normally
- Email will send and receive normally
- Email and URL forwarding will operate normally

Namecheap anticipate the maintenance will only last up to eight hours.

Calculating Pagerank with matricies

Google pagerank is calculated as a function of how many pages link to you, and how many pages link to the pages that link to the pages that link to you, and so on.

Evidence suggests that this pagerank is calculated by google using Matrix calculations, not least, because it would be much faster to calculate.

Here is how it is done.

Imagine six web pages, that interlink as shown
(See image Left)

From this, we create a 6x6 matrix, where the rows represent pages, and the columns represent links to other pages.

A "Link" is a Matrix cell in the format 1/x where x is the total number of out-links from that page. So 1/2 means that there are 2 out-links.

This is the Matrix shown in Fractions (above). This needs to be converted to decimals, so I can feed it into Wolfram alpha for the calculations:

To calculate the pagerank, we need to pre-multiply it by a matrix {1,1,1,1,1,1} known as the Pagerank Vector.

This then yields the result:

Which shows, in relative importance, which page would be deemed most important, in this case "1.5" which is Page 4.

Price comparison for .gr (Greek) domain names

Shopping around for a .GR (Greek) domain name, I came up with the following prices - 20 Euros / 2 Years - 17 euros / 2 years - 17.85 euros / 2 years - 23.68 euros / 2 years - 19.04 euros / 2 years - 20 euros / 2 years
EuroDNS - 35 Euros / 2 years

The two cheapest, and don't have an english version, however, many common words are in english, but to be honest, I prefer to pay an extra 2 euros, to be more comfortable that I don't have to rely on Google Translate to deal with tech. Support.

A few second level domains are emerging in Greece, such as the common,,, and the less common, and the newly promoted

In Greece, the Greek alphabet is used rather than the latin alphabet, so IDN domains are rising in popularity, but it is still possible to transliterate words from Greek to Latin.
