Denial of Service attacks
A Denial-of-Service (DoS) attack is an attempt to make a machine or network resource unavailable by overloading the target system with traffic. These attacks can originate from multiple IP addresses at the same time; this is called a Distributed Denial of Service (DDoS) attack.
This can cause the victim to experience slow speeds or a loss of Internet connection in general.
I’m being DOS attacked, what can I do? I’m being DOS attacked, what can I do?
If you suspect you are the victim of a Denial of Service attack, the best course of action to take is to report the incident to the Internet Service Provider (ISP) that owns the IP addresses that are attacking you.
You can identify the IP address(es) committing the attack by looking through the Firewall and Network logs of your router and picking out the IP addresses that are shown as sending excessive traffic your way.
In order to identify what ISP you need to report the incident to, you should run a Whois lookup on the IP addresses that are sending the excessive requests. You could use www.ping.eu* to help you do this.
The result of that lookup should state what ISP owns the IP in question and it will normally have the contact details to send Abuse reports to – in most cases this is an email address such as abuse@<ISP’s Domain>
Can you change my IP address? Can you change my IP address?
No, we cannot change IP addresses for individual customers. If you are using a Super Hub or Hub 3.0 you could boot it into Modem Only mode until the attacks stop – this will provide you with a different IP address while you are in Modem Only mode.
Be aware that Modem Only mode on a Superhub only provides an Internet connection over one Ethernet port, and wireless access will not work. You can however attach a 3rd party router to the Superhub to use its wireless and firewall facilities if you have one.
