I need to update my domain's IP address and am not sure how to do it. Would appreciate any help you can provide. Thanks!
It sounds like you have the proper information from your web host, you'll just need to input them into the DNS manager. Here is an article that should help:Manage DNS for Your Domain Names
One of the considerations in updating your domain's IP address is whether it needs to be on the C record or the A record. For example, if you have a manged wp hosting, an IP address is provided when you create the installation and you only change your A record.
A second example would be hosting on a cloud server provided a hosting company other than GoDaddy. Many of these installations, require the IP address to be changed on the C record. In this case, you'll need to make sure that all of your MX records which control your email services are properly configured. In cases where C record changes are required, I highly suggest calling support to walk you through the process. Its much more detailed than an A record update.
Hope this helps,
