I am looking for a domain name registrant. Where can I look it up?
The Whois is an easy-to-use tool for checking the availability of a .nl domain name. If the domain name is already taken, you can see who has registered it.
On the page looking up a domain name you will find more information about what a domain name is, how the Whois works and how the privacy of personal data is protected. Alternatively, you can go straight to look for a domain name via the Whois.
I would like to transfer my domain name to another registrar. What is the procedure?
To get your domain name transferred, you need the token (unique ID number) for your domain name. Your existing registrar has the token and is obliged to give it to you within five days, if you ask for it. The procedure for changing your registrar is described on the page transferring your domain name.
The details registered about me/my company are incorrect or out of date. How can I get them updated?
To update the contact details associated with your domain name, you need to contact your registrar. Read more about updating contact details.
Why is my domain name in quarantine?
When a domain name is cancelled, we aren't told the reason, so we can't tell you. You'll need to ask your registrar. The advantage of quarantine is that, if a name's cancelled by mistake, you can always get it back.
One common reason is that the contract between you and your registrar says you've got to renew the registration every year. If you haven't set up automatic renewal and you don't renew manually, the registration will expire.

Without effective defences, DDoS attacks could have cost the Dutch business community and government more than a billion euros in lost income last year. That's the conclusion of research into the economic impact of DDoS attacks in the Netherlands undertaken by the Dutch National Internet Providers Management Organisation (NBIP) and SIDN (the Foundation for Internet Domain Registration in the Netherlands).
NBIP and SIDN presented their report The impact of DDoS on Dutch enterprises on Monday 19 November. The research brought together data from NaWas (the national traffic scrubber, set up by NBIP) and data held by SIDN about the organisations behind the affected .nl domain names, which SIDN manages.
By pooling their data, the two organisations were able to estimate that NaWas-affiliated enterprises would have missed out on 425 million euros of earnings if they hadn't been protected. Given that NaWas protects 43 per cent of .nl domains (2.5 million), and that SIDN's data relate exclusively to .nl domain names (64 per cent of all domain names in the Netherlands), the total potential losses associated with DDoS attacks is likely to be a lot more than 450 million. What's more, the researchers didn't have any data about various large organisations with their own anti-DDoS solutions.
Sectors
Major differences were found between sectors. It's also important to distinguish between enterprises that are targeted by attackers, and those that are victims of 'collateral damage'. The potential repercussions of a targeted attack are greatest for government agencies: nearly 60 million euros. Home and Garden is the sector liable to lose most in collateral damage (35 million euros).
Collateral damage occurs when an enterprise shares a host with a targeted organisation. A website with a shared host is 35 times more likely to be affected by a DDoS attack than one with a VPS or dedicated host.
Awareness
Enterprises therefore need to consider what hosting services suit them best. With faster and cheaper solutions coming on line all the time, going for the lowest-price option isn't a risk-free strategy. "Hosting service providers need to recognise their responsibilities as well: they should be explaining the risks that come with shared hosting," says NBIP's CEO Octavia de Weerdt. "We hope that our research will help to build awareness of the problem, both amongst service providers and amongst service users."
As Michiel Steltman, Director of Digital Infrastructure Netherlands (DINL), says in the report: "Most companies nowadays have on-line activities that rely on cloud infrastructure or hosting. And price is often the main factor influencing their choice of service. However, with DDoS attacks on the rise and the legal obligation to protect personal data, security and the ability to resist attacks should be a much higher priority."
Economic impact
The economic impact was assessed by estimating the earnings that would have been lost without protection. The calculations were based on turnover figures for the affected enterprises and the duration of the attacks.
"We don't pretend that these are precise numbers. As the Netherlands Bureau for Economic Policy Analysis concluded in October, the exact cost of DDoS attacks is very hard to quantify. For example, if a website isn't available for a day, how many sales are lost altogether and how many are simply delayed?" says Michiel Henneke, SIDN's Marketing Manager. Another complicating factor is that the study was to a significant extent concerned with potential losses: actual losses are often avoided by the use of anti-DDoS defences, such as NaWas.
NBIP and SIDN therefore hope that their joint study will serve as a trigger for further research.
"In the Netherlands, there has been almost no research into the financial implications of DDoS attacks. It's a difficult topic, because how do you measure how disruptive something is for the community? So we're hoping that, in partnership with SIDN, we've started a ball rolling," says de Weerdt. "We're calling on government bodies, market players and other actors to turn their attention to the economic impact of DDoS attacks."
