Domain Trademark

[hostele]

Hello everyone,

I have registered a nice keyword (.com) domain name which was dropped and i found that there are many established companies having the name in different extensions.

Lets say that the domain name for example is HostCity.com and the other companies are HostCity.net or CityHost.com, etc

Is this is a trademark issue ?

How can i know which domain name was created first, and if the domain i hold was created first, does this make me safe.

I would appreciate all kind of inputs.

look at the whois of the domain names
do you plan to park or develop the name? if you develop, then makesure you dont infringe on content
