Over the years, I have advised my clients to make sure you OWN MANY DOMAIN names for your business.  Now in politics you can really see the danger of not buying up those domains with .org, .com.  Now if you don't care, if your companyname.org goes to a different place, then no worries.  However if you are concerned about your business 'ownership', make sure you own domains with different extensions and that they all point to YOUR website!

An example of domain names gone wrong is, jebbush.com and tedcruz.com.  A domain name will only cost you at most $20 per year...think about that!  This doesn't mean you need to purchase every single iteration of your business name, but it is a good idea to get a few...or else someone finding your company...may be brought to your competitor!
