Domain: Zong.Zong.Co.Ua

Domain: zong.zong.co.ua

If you are seeing queries for this domain, than you are likely participating in DNS Amplification attacks and your DNS server is probably reachable from the internet and has recursion enabled.

If you are seeing responses for this domain.. unlucky. You are currently beeing DDOS-ed! Good luck.


IPtables:


There are two iptable rules available. If your distribution supports Iptables 'u32' module pick this one, otherwise use the 'string' rule.

U32:
iptables --insert INPUT -p udp --dport 53 -m u32 --u32 "0x28&0xFFDFDFDF=0x045a4f4e && 0x2c&0xDFFFDFDF=0x47045a4f && 0x30&0xDFDFFFDF=0x4e470243 && 0x34&0xDFFFDFDF=0x4f025541 && 0x38&0xFF000000=0x00000000" -j DROP -m comment --comment "DROP DNS Q zong.zong.co.ua"

More U32 rules can be found here:

String:
iptables --insert INPUT -p udp --dport 53 -m string --from 40 --to 57 --algo bm --hex-string '|047a6f6e67047a6f6e6702636f02756100|' -j DROP -m comment --comment "DROP DNS Q zong.zong.co.ua"

  10. Once a domain expires one of two things will happen. Firstly the domain will expire and become available to register as a domain name through the normal registration process. If the domain has any value then it is likely to be picked up by a name drop registrar.

    Before we go deeper into the world of dropped names you may want to know what an expired domain name is and how you go about getting hold of an expired domain name.

    You may have noticed that your registrar offers a back ordering service. A Back order service allows you to pay your domain registrar to try and acquire a specific domain name once it expires.

    There are drop registrars whose sole purpose is to try and register a domain name once it has dropped. These expired domain name catchers work on behalf of individuals and other domain registrars to acquire domain names on their behalf.

    Expired domains are a big business as webmasters and large corporations try to grab as many valuable domains as they drop. The reason for this virtual land grab is that many domain names can fetch high resale prices on the open market or have valuable existing traffic or type in traffic potential.
