Usually yes, but there’s something to consider: If you have a dynamic IP address, you’ll probably use some dynamic DNS service to forward your domain to (e.g. example.org → some-dyndns.org → your server with a dynamic IP). This is one more step compared to a static IP (example.org → your static IP), and you have to trust a third party (the dynamic dns provider, except you host it yourself, which is possible too).
Also, if you use CNAME/DNAME to forward your domain to the dyndns address, the dyndns provider could misuse this (e.g. hosting its own site on your domain).
