It wants you to put in whatever nameservers you will be using. It's pretty nice, it's even offering you glue records if you're to self host your DNS too!
Most domain registrars tend to also offer DNS services and even default to using theirs, so it's often thought those come together. It seems like eu.org doesn't. So you have to provide your own. That could be Cloudflare or any number of DNS providers out there.
Most of those DNS providers will give you two name servers that you can input there. Minimum is 2 but some have 4 and 8 too, but it's rare. You just put them there for the first two and you can leave everything else blank.
You need to host your domain somewhere, meaning some DNS provider needs to be the authority on what gets routed where when someone accesses your domain.
The provider will give you a list of nameservers when you make the domain part of their DNS.
I don't know if there are any that are free (if you don't also buy a domain from them), so you'll have to check on your own. You can also self-host a bind9 server and do your DNS there.
bunny.net is technically $1/mo but you don't pay anything in months where the queries against their servers fall under a threshold. With a low use personal domain you can basically load up $10 worth of credit and coast on it for a year or more.
Please don't self-host DNS. It can be exploited and abused in many ways if you don't know what you're doing.
Seconded
One of these is DNS reflection, a type of amplification DDoS I found out about several years ago... You send a tiny packet to a DNS server requesting a domain with long records, but tell the DNS server to send the response to another address. Pretty interesting and amusing imo, but probably not if you're on the receiving end of one lol
Do either of the options you mentioned provide custom nameservers? As in, the ability for ns01.yourdomain.com to resolve to your account on their DNS servers?
When you buy a domain you get the "right" to that domain, and nothing else. You then need to provide (either your own (not recommended) or through a service) DNS servers which will translate those names to IP addresses for you.
At that point any and all domains under the one you registered are in your control. Any requests for domains under that one will be directed to your DNS servers.
Sometimes the registration and domain management are provided by the same companies.
they ignore all requets.
i have a couple of pp.ua domains, and there's no limit on them (you cant register more than 3 per month)
but unfortumately one of the requirements is that you can't hide phone number and address from WHOIS records and you must provide them your phone number
Here's the thing, I was able to request one and never got it. Maybe they are simply ignoring new requests, who knows. Other users already replied to your question.
My understanding of name servers are where is your domain going to be recorded. For instance, my domain may be something.com but the name server tells the browsers to send the web traffic to 50.50.50.50 where the server lives.
