Dynamic IP vs IP Fix

[krooze]

Hello,

i just install Vestacp on my pc with CentOS 7

my internet ip is dynamic i configurate centos 7 with a IP fix 192.168.1.xxx

for dynamic ip i use no-ip.org for exemple my dynamic ip is: 90.123.8.111

now... lets go to vesta panel

when i create a domain in vestacp using my domainname register on other service..they put my dynamic ip "90.123.8.111"


i go to my hosting service and i register a glue records:

ns1.mydomain.com > 90.123.8.111
ns2.mydomain.com > 90.123.8.111

jump to vesta panel

and create a new DNS:

ns1.mydomain.com > 90.123.8.111
ns2.mydomain.com > 90.123.8.111

i use this site to check the dns https://dnschecker.org

but dont work

What am I doing wrong?

PS: sorry my english
