: DNS sub-domain registration Is it possible to register a sub-domain if you don't own the base domain? For example, could I register NickLarsen.random.com if I don't own random.com?

@Reiling115

The general you should believe is Oren's - however there is one exception to this rule.

If a domain is using freedns.afraid.org/ as their DNS provider and they've been lazy and not read the fine print, then anyone can create an A record as a subdomain to any domain listed on their site.

If you take a stroll around their site you can find a list of all the domains they have avaliable that you can create your own subdomain of.

Well, you could, technically speaking (configuring a DNS server for yourself, adding a zone file for the domain in question and creating an A or CNAME record for the subdomain in question), but it would work only for the people that use your DNS server to resolve domain names, so it really wouldn't work for that many people. And that's a good thing, because otherwise the Internet as we know it just wouldn't be, and there would be no real trust that you're actually on your bank's website or on a phisher's website.

No. This is not possible unless the owner of the domain allows it.

As per Wikipedia:


The Domain Name System distributes the
responsibility of assigning domain
names and mapping those names to IP
addresses by designating authoritative
name servers for each domain.
Authoritative name servers are
assigned to be responsible for their
particular domains, and in turn can
assign other authoritative name
servers for their sub-domains.
