So, if I SSH into my server, and if I do "curl http://myip.dnsomatic.com", it returns 108.172.183.121. If I Google my IP Address on my computer, it says my IP Address is 108.172.183.121. My modem says that its "Modem IP Address" is 108.172.183.121. I did reboot my modem few times. Now, my router is set to DHCP and my Linux server doesn't have a static IP address. I might be missing something here. Do I have to configure my server, or my modem to change my devices' IP Addresses?
