I have updated a domain name DNS zone on 123-reg.co.uk where I bought the domain name. I have only updated blog A record to different hosting(IP)
On my PC home (windows) or another PC in the same network (MAC or phone) when I visit the blog.domain.com still shows old IP address (hosting).
But when I connect to 4g on my phone or try from different network, they visit new IP (hosting)
did ipconfig /flushdns
I have restarted the router at home.
I have cleared browser cache
Why do you think the reason is? How can I solve this?
