Kevin has a domain name and he can't get his registrar to respond to him. Leo says he'll need to contact ICANN. They are the governing body, and there he can submit a dispute demanding that he get his domain back. According to the WHOIS, the company he'll need to contact is Tucows. They are probably the new owners of that registrar.
Lee wants to know how to register his domain and DNS so he knows he owns it. Leo says that ICANN is a non-governmental organization that handles the DNS "phone book." They maintain 13 main DNS name servers, and his domain name needs to be on one of those servers. He'll have to go to a registrar that's been approved by ICANN. GoDaddy is one such registrar, but Leo isn't a fan of it. He prefers Hover. If he wants to change registrars, he can do that. But he'll have to jump through a hoop or two to do it.
Sonny wants to use a domain name and he can't get the one he wants through GoDaddy. Leo says that GoDaddy may have bought it and will then turn around and try and sell it back to him for a higher price. Some believe they watch domain traffic and if he doesn't buy it, they'll snap it up. People don't have to build a website to buy a domain. They just buy them to reserve the domain for a later use. Others, though, cyber squat the domain and then scalp it, which it looks like GoDaddy is doing, and that's not the right thing to do.
Chris wants to get a domain name for a specific country. Leo says that the international organization called ICANN approves registries and country codes for all domains. Leo suggests Google searching for the domain registry for his country code. Any registrar will work if they support registering the country code he wants.
AmericaRegistry.com is a good place to start. But he may run afoul of laws pertaining to that country. Brazil, for instance, requires a Brazilian tax ID to buy a domain with their country code.
Sean made the mistake of transferring his domain name in the middle of a Kickstarter campaign. Now he is struggling with time outs. Leo says that Sean needs to talk to the domain registrar. But it takes time moving nameservers from one host to another. He might have to contact the original host and get them to release the domain name so the other host can pick it up. If he's hosting the site at home, then he'll have to run a domain server. This is the main reason why he shouldn't host the site at home.
Trevor is frustrated with GoDaddy because he searches for domain names, but when he goes back to buy them, GoDaddy has bought it and increased the price. Leo says that that's why he uses Hover. They don't do stuff like that.

Brian's domain name expired and he can't access his website now. Leo says that if Brian paid someone to do his website and let them register it, chances are they own the website domain and not Brian. It's a very common practice. Sometimes, they can fall off the map leaving him unable to renew his domain.
