I will give you another good tip:
If you are a provider - providerdomain.tld - with your client (clientdomainname.tld),
then try to avoid the following DNS-construction:
clientdomainname.tld
ns1.providerdomain.tld
ns2.providerdomain.tld
Use this solution:
Register a 2nd providerdomainname for you as a provider.
Use this domainname as the 2nd DNS-name. Then you make
clientdomainname.tld
ns1.providerdomain01.tld
ns2.providerdomain02.tld
You should also take care for the .TLD. Do not use both .TLDs as
.COM or .NET or .ORG. Try also to be very different there. The
best would be to use minimum one
ccTLD (=CountryCodeTopLevelDomain) for it, f.e.
clientdomainname.tld
ns1.providerdomain01.tld (in your case: .GR for Greece)
ns2.providerdomain02.tld (.NET)
Because of 2 different .TLDs, you can also melt providerdomain01
and providerdomain02 to one providerdomain, which means:
clientdomainname.tld
ns1.providerdomain.tld (in your case: .GR for Greece)
ns2.providerdomain.tld (.NET)
For a computer, the registry and the registration-center, an
EXAMPLE.GR
EXAMPLE.NET
are 2 different domainnames although both have the same name
"EXAMPLE". Some Plesk-users are from Belgium, Italy, Germany
or USA. They should just use their own ccTLD alike .BE, .IT,
.DE or .US.
If you understand this construction - which you can do with
Plesk by a very easy way, here...
clientdomainname.tld
ns1.providerdomain.cctld
ns2.providerdomain.tld (.NET)
..then try to consider about the next step. Try to avoid
ns1
ns2
It is better to give it a better name instead of this "wannabe-standard"
ns1 and ns2. Try to find out in which city and place this DNS-machine
is located.
For example, in your case, if you are located in Crete Islands
in Greece, then try to use
clientdomainname.tld
crete.providerdomain.GR (=ccTLD)
anothercityname.providerdomain.NET (=gTLD)
For example, if you backbone-connection goes from Crete
Islands in Greece to Rome in Italy, then use
"rome.providerdomain.NET". Another example would be, if your
Plesk-Server is not located in Greece. It's located in
Redmond, WA (USA), then use "redmond.providerdomain.gTLD
(.NET).
Background: Many hackers and many uncontrolled robots in the
internet always try to use the "wannabe-standard" with ns1
and ns2, because they always try at first the
"DNS-beginners". It is a theme about the security to protect
your DNS and your BIND.
Here again the overview with the final result:
-------------cut----------------
clientdomainname.tld
=================
yourcityname.providerdomain.ccTLD (f.e. .GR for Greece, .DE for Germany, .US for USA, etc.
anothercityname.providerdomain.gTLD (.NET)
-------------cut----------------
We can also talk about examples in the internet. You see then
very well, if a network-construction was done _professional_
or risky. Remember always this -cut-cut- from the lines above
and look to some examples with some comments by me:
MICROSOFT.COM
==============
NS3.MSFT.NET
NS1.MSFT.NET
NS5.MSFT.NET
NS2.MSFT.NET
NS4.MSFT.NET
= unprofessional.
1) If .NET will be down, the complete MICROSOFT.COM will be offline.
2) if MSFT.NET will be down, the complete MICROSOFT.COM will be offline.
3) They use the wannabe-standard ns1, ns2, ns3, ns4, ns5. Easy to hack.
IBM.COM
=======
INTERNET-SERVER.ZURICH.IBM.COM
NS.WATSON.IBM.COM
NS.ALMADEN.IBM.COM
NS.AUSTIN.IBM.COM
= unprofessional.
1) If the .COM will be down, the complete IBM.COM will be down.
2) If the IBM.COM will be down, the complete IBM.COM will be down.
3) A lilttle bit better than MICROSOFT.COM are the given names
to the DNS. They use "zurich, watson, almaden, austin". But it
is not perfect, because they all are totally dependent from the
IBM.COM.
CNN.COM
========
TWDNS-01.NS.AOL.COM
TWDNS-02.NS.AOL.COM
TWDNS-03.NS.AOL.COM
TWDNS-04.NS.AOL.COM
= unprofessional
If .COM or AOL.COM will be down, then
http://www.cnn.com is offline.
SW-SOFT.COM
============
NS1.SW-SOFT.COM
NS2.SW-SOFT.COM
NS3.SW-SOFT.COM
= unprofessional
Same reasons like MICROSOFT.COM and IBM.COM.
The best one thing is, that if SW-SOFT.COM will be down, then
the Admin and TechZone of SW-SOFT.COM will not be able
anymore to update the registry, because they also use the
sw-soft.com for email.
Here again:
-------------cut----------------
clientdomainname.tld
=================
yourcityname.providerdomain.ccTLD (f.e. .GR for Greece, .DE for Germany, .US for USA, etc.
anothercityname.providerdomain.gTLD (.NET)
-------------cut----------------
ccTLD = CountryCodeTopLevelDomain (see also ISO 3166)
gTLD = GenericTopLevelDomain (.NET, .COM, .ORG, .INFO)

Point-to-Point Tunneling Protocol for creating Virtual Private

what exactly do you need this?
