Get an account to use NTRIP services.

Most public and private NTRIP Casters are “closed” in that you must first register with the owner/operator before your NTRIP client software can connect and get any data.  

Contact the operator of any NTRIP Caster you wish to connect to in order to understand how to register on their network.  Some networks, or some streams within some networks, involve monetary compensation for the operators like  https://register.rtcm-ntrip.org/cgi-bin/registration.cgi

What about free NTRIP Caster ?

SNIP also operate a free open NTRIP Caster at RTK2go.com which any party can use to send their data to.  Use this resource to send your Base Station data to others.  This allows those without a static IP, or if they do not want to operate their own Caster, to provide corrections to others (or themselves).  The RTK2go.comCaster is one of a growing number of free open Caster services now on the market as the deployment of RTK style navigation grows.
