Wondered why companies like Google have their nameservers named like ns1.google.com ?, rather than ns1.SomeOtherCompany.com ? - its' a performance tweak, that I'll demonstrate with a detailed lookup as follows:
DNS speed check for www.google.com
Probing k.root-servers.net for 'A' record for www.google.com.
Refered to b.gtld-servers.net. [Time 426 ms]
Probing b.gtld-servers.net for 'A' record for www.google.com.
Refered to ns3.google.com. [Time 81 ms]
Probing ns3.google.com for 'A' record for www.google.com.
Found, 'A' record for www.google.com. [Time 111 ms]
See, three lookups, one for .com, the other for .google.com, and finally www.google.com
Now, compare that with freenameservers.co.uk, whose nameserver is not on the same domain
DNS speed check for www.freenameservers.co.uk
Probing k.root-servers.net for 'A' record for www.freenameservers.co.uk.
Refered to ns2.nic.uk. [Time 337 ms]
Probing ns2.nic.uk for 'A' record for www.freenameservers.co.uk.
Refered to ns1.telivo.com. [Time 84 ms]
Probing k.root-servers.net for 'A' record for ns1.telivo.com.
Refered to b.gtld-servers.net. [Time 366 ms]
Probing b.gtld-servers.net for 'A' record for ns1.telivo.com.
Refered to ns0.ai270.net. [Time 84 ms]
Probing ns0.ai270.net for 'A' record for ns1.telivo.com.
Found, 'A' record for ns1.telivo.com. [Time 97 ms]
Probing ns1.telivo.com for 'A' record for www.freenameservers.co.uk.
Found, 'A' record for www.freenameservers.co.uk. [Time 84 ms]
Six lookups in total, one for .uk, then .com then telvio.com, then ns1.telvio.com, then freenameservers.co.uk. then www.freenameservers.co.uk
So, in short, if you have the option, you should always have your nameservers named the same as your primary domain.

DNS in IPv6
IPv6
In the introduction we would like to mention "the next generation Internet, or IPv6. You've probably already heard that the current IPv4 protocol is slow breath. Address space is nearly exhausted and, according to preliminary estimates, free IP addresses run out completely in 2012. Moving from zastarávajícího protocol to the new world is very slow and the content of IPv6 is still not much. Therefore, the users of this "news" too interested, though they will have many benefits. For example, with its huge address space of each device will have a so-called public address accessible from anywhere mobility, the automatic configuration and increased security through many mechanisms.
We would provide these benefits to you, our customers. We try to encourage and accelerate the transition to IPv6, and we are on the network to make available all our services. More information can be found at the end of this newsletter.
Overview of the occupied area
For hosting customers, we have prepared pie charts illustrating the use of their space in the purchased fare. In them it is apparent distribution space in the data to FTP, e-mails, databases and backups. At first glance, you may startle amount of space occupied on backup server. Security of data entrusted to you is our priority and therefore, all data is backed up regularly and carefully. We keep you for seven backups of all systems - the last five days and the last two months. So if you accidentally lose any data at your request, we can recover.
OnlineDNS - added support for SRV and AAAA records
In our application for managing DNS domains our management we have added support for SRV and AAAA records. AAAA record is used to translate domain names to IPv6 addresses and is similar to the IPv4 A record. SRV record specifies information about available services. Commonly used for SIP services (voice calls), XMPP (online communication and data exchange, typically Jabber), LDAP (directory server data), then records of this type requires such GoogleApps.
News in the Client section
If you have a large number of domains, you will appreciate the opportunity to sort by expiration date or title. All customers are also displays the icon "Pricelist domain" is hiding under the table is arranged with the prices of existing domain account for the client section.
Custom Windows Server only for 390,-CZK per month
In the event of the deployment radically reduces the cost per virtual serverhosting using the Microsoft Windows Web Server 2008 R2 with a dedicated 1 GB, 2 GHz processing power, 30 GB hard drive, a guaranteed 100 Mbps connectivity to the Internet and a full administrator access to Remote Desktop using RDP and IIS Manager for Remote Administration. Price of hosting fare is more than dvaapůlkrát higher and amounts to CZK 990 per month.
On the server you can install software for statistics, control panel, mail server or hMail popular CMS Kentico CMS Free Edition - We are the authorized hosting partner. Virtual serverhosting on the Microsoft Windows Web Server 2008 R2 is also ideal for beginning Web developers who can run it on my first application with minimal cost.
More about virtual serverhosting for CZK 390 per month can be found here: http://www.web4u.cz/serverhosting/vs_windows
More information on IPv6 - deployment for customers and hosting serverhosting
IPv6 newly assign serverhosting customers on demand, or our Web hosting customers come in short. Our hosting services are also available via the new network. So if you want your website presentation on the IPv6 network, simply add the appropriate entries in DNS. Addresses 2001:1568:: 10 when using PHP4 respectively. 2001:1568:: 11 for PHP5. Our technical support will be happy to advise you where to make your application settings.

Price comparison of Slovenian (.si) domain names
I compared a number of Slovenian domain registrars for prices for one year for a .si domain, with no hosting.
tld-registrar.com - €30 / year
101domain.com - $119 / year
slovenia-domain.com - €16.80 / year
domene.si - €19.96 / year
domovanje.si - €15.59 / year
domenar.net - €14.90
hitrost.com - €15.54
Gigaspark.com - €18.90
The cheapest of the providers that had an english option was slovenia-domain.com at 16.80 euro. They also had a paypal option, so this is the one I chose.
domenar.net also appeared to have a paypal option, but it didn't work when I tried it.
All the other providers required a bank transfer as a form of payment, and had no english option. their sales support spoke english, and were even happy to zero rate the purchase for VAT, meaning that it would have been possible to order the domain for €12.95 from HitTrost.com
