The address your connection to the IRC network originates from may be displayed to other users and may be logged by connected servers / devices.
In most cases, having your IP address displayed in this way is of little or no consequence.
You will be asked questions regarding your safety, feelings, social situation, and if you have any thoughts of suicide.
If a chat counselor feels you are in danger they will speak with you about accessing emergency services, and/or gather additional contact information to ensure your safety.
All chat centers in the Lifeline network are accredited by CONTACT USA. Anyone who is depressed, going through a hard time, needs to talk, or is thinking about suicide can use the chat.
