Assuming you'rein the USA and the IP that is sending pings to you is in the USA, you should be able to report it so your ISP. It is illegal.

Assuming your ISP is like most, you can typically change your IP by powering down your modem for a few minutes or changing the MAC address on whatever device is getting an IP from your ISP.

Can you block IP addresses? If so, then block his IP address.

What do you mean when you say "he has my skype"?

Also, what firewall program are you using?

There is a major security exposure in skype and microsoft could care less. If you know someone skype id you can find the current/last ip they used their skype from.

Firewalls are completely useless. The traffic is already being dropped by his router likely. Even if you were to block it the damage is already done. It's as if someone calls you over and over on the phone. Answering and telling them to stop is as silly as thinking it can be fixed with a firewall rule.

Only the ISP can stop this and they likely will not bother until you get court orders.

Blocking is just another word for "ignoring". It doesn't stop it from happening.

These answers are less than accurate, You can totally block an IP address, You can completely handle this. First things first, Find his IP with skype, Block him on Skype, And add a rule in your firewall to ignore all packets from him, You can easily do this in iptables if you were on linux which I assume you aren't. That is TOTALLY possible and will completely work, Also, In your router, You can easily just tell it to ignore ping floods, However, A DoS attack isn't necessarily a ping flood, that is just one means by which it can be achieved.

Also, A ping is a completely useful, And legal, Not necessarily harmful thing. It is just a little thing to ask a computer if it is alive or otherwise connected to said network/accessible. Also, Here are some possibly helpful guides for blocking an IP address on windows, Mac OSX, And linux.

Also, Maybe just get a new skype account and a new account on League of Legends and what ever. Also, Check what information you have visible on Skype and League of Legends, They may be able to see your email address, So you may want to use a new one. You could, Also, Just google yourself to see what comes up, And maybe change some stuff as to not be as easy of a target. Regardless, You don't *need* to do this, Just do the stuff below, You can easily block any IP he uses to attack you. You could use skype to keep getting his IP if he tries to change it, So you can just add it to the list again.

Also, You should be able to check in some log file or what ever or maybe an app what IP is connected to you and sending you stuff, The one that is spamming you a lot is most likely him, So just block it through the following means. Regardless, You can always respond to me here and I will see if I can do anything else to help you. More information would be helpful.

Maybe you should learn to read some of the guides you post before you claim things are not accurate.
You are a fool if you think you can stop a Dos attack yourself.

You obviously have no idea how skype works if you think it is in any way related to blocking someone on skype. If I have your skype ID I can get your IP. Pretty much the second you log into skype skype will in effect broadcast your ID and IP address into its network. It sends it to everyone. You have no control at all over this. You can prevent me from calling or sending you mail but you can not prevent skype from telling me your IP.

It will not "TOTALLY" work to just ignore his packets. That is like saying I can turn the ringer off on my phone so it doesn't ring when someone calls over and over and over. And it is much worse since a phone at least nobody can ring you while you are using it. With a DoS attack the packets keep eating your bandwidth even if you ignore them.

Besides nobody is stupid enough to send stuff from their own IP. This is all done with bot nets to send from many thousands of different IP. With the skype one it is as simple as go to a web site type in the skype address put in how long you want to attack and put in your bit coins or credit card. So even calling you ISP and asking them to block a particular IP address in their equipment will not work.

Why you think you can just read a guide and magically fix a denial of service attack is just crazy. Do you not think the professionals in this field know everything in all those guides and it still seems we have every major game company being attacked on their release date lately. When a company that has huge resources only way to stop this is to work with their ISP to do it how do you think reading some silly guides and putting in firewall filters will stop this.

Bottom line is you can not stop a denial of service attack by configuring stuff in your house the damage is done the second the packet leave the ISP on the path to your house, your bandwidth is used up at that point and you can not undo that.
