Setting domain records correctly based on predefined ones

by lesssugar   Last Updated January 12, 2018 17:04 PM

I bought a new domain (let's call it example.com) from a domain provider (let's call it provider.com).

I would like to point the domain to my server. The thing is that the provider automatically created lots of domain records out of the box:

+------------------+-------------+------------------------------------------------------+
|       NAME       | RECORD TYPE |                        VALUE                         |
+------------------+-------------+------------------------------------------------------+
| ipv6.example.com | AAAA        | (IPv6 address)                                       |
| example.com      | MX          | 10 example.com                                       |
| example.com      | A           | (IPv6 address)                                       |
| example.com      | NS          | dns.provider.com dns2.provider.com dns3.provider.com |
| example.com      | SOA         | dns.provider.com admin.provider.com                  |
| example.com      | TXT         | "v=spf1 mx a ptr ~all"                               |
| mail.example.com | CNAME       | example.com                                          |
| ftp.example.com  | CNAME       | example.com                                          |
| www.example.com  | CNAME       | example.com                                          |
| *.example.com    | CNAME       | example.com                                          |
+------------------+-------------+------------------------------------------------------+

What I originally wanted to do, was to add a new A record and 2 CNAME records for www and subdomains. But with all the records the provider set, I'm not sure which records to touch now.

Generally speaking: which records do I need to change and which not?

More specifically: I assume that I still want to update the A record to the IPv4 of my server. But what with the AAAA / MX / NS / SOA records? And further: what with the mail and ftp subdomain entries?
