Connections made by ip address to the ispconfig controlpanel are not affected by dns settings. If you cant connect to port 8080 when using the ip address, then you might have blocked it with the firewall or apache is not started.
You can check that with the iptables and netstat ommands.
If you want to edit dns records manually, take a look into the bind configuration file directory, there you will find the named.conf.local file.
