Does anyone have experience of changing DNS settings?
The general view is that:
These changes may take a while to implement.
How long is “a while”? An hour? 24hrs? 48hrs? A week?
In any type of fault finding it’s essential to be able to test changes against expectations, but if there’s a delay then it’s equally essential to understand when the changes are likely to have been implemented.
I am self hosting a website and using dynu to redirect my domain to the right IP when the ISP changes the IP address. I have configured dynu settings in my router’s DDNS configuration
DNS does propagate quickly but it depends on your domain registrar.
GoDaddy for example doesn’t instantly send your changes. They wait possibly to batch DNS changes for all their customers. This it can take 24 hours with them.
I use hover.com and DNS changes take minutes to an hour.
