Something need to be done about racial abusement

If someone's being abusive, file a complaint on them and block communications with them.

need to have reasons for reporting like the old system i.e racial abuse/bad language/bad sportsmanship etc to clarify

If you are worried about your IP address being taken, I suggestion buying a VPN router or, running a VPN service through your router.

Unfortunately there's not much that can be done in regards to a DDoS attack.

To be perfectly honest, the likelihood that they are getting your IP address is unlikely as Xbox is provided with a private IP address (provided by router).

You have 2 IP addresses, one public and one private, The public IP address is the IP address assigned to you by your ISP.

In the instance it is happening, there are a few things you can do to prevent it. Like applying a filter to your router to drop packets from a specific address that you can obtain using specific networking
software.

However, I'm not able to provide the information as it's not really an Xbox issue, I can only give advice and point in a right direction.

I hope this information has somewhat helped.

Sorry to hear it. Xbox does not allow others to get the IP address from their service, people use outside links to get into that info which is pretty much available to anyone if you know where to look.

As for personal info, an IP address only gives a general area as to where you are connecting from. It sounds like the other person was running your IP address into a website that was knocking you offline.

A DDoS attack is illegal and could result in the person doing it facing jail time. If you're attacked unplug your modem/router for 5 seconds to fix it. You should also report the attacks to your ISP and request a new IP address. They will also investigate
the attacks and take any necessary action on their end.
