Hi everyone

Ive recently become aware of the 1.111b class domains from xyz and decided to buy one. They have serveral purchasing options from either themselves, namecheap, dynadot, porkbun, godaddy. All of these sites have slightly different options and prices. I like the idea of buying a 10 year lease too, not all of the providers have that options

What im wondering

1. Do i need WHOIS privacy?
2. Do i need SSL support?
3. What else should i know before committing to buying a domain
4. Do i need to use my actual details when registering a site? I dont like the idea of anyone being able to look up my personal information just because I have a domain for a server (but perhaps thats just the price of admission)

Thank you for reading, this is my first time buying a domain and i want to make sure i do it properly
