Swedish hosting provider Binero has announced that it has DNSSEC-signed all of its customers’ .se domains. This brings the total amount of signed .se domains to more than 100,000 from the previous total of 5,000.

“Nearly one in ten Swedish domains are now validated against attacks with manipulated dns-information, like phishing,” Binero’s press release said.

It’s hard to find any worldwide numbers to compare to but ICANN reported yesterday that 88 TLDs (Top-Level Domains) are DNSSEC signed.

But what is DNSSEC (Domain Name System Security Extensions) and why should you care whether your domains are signed with it or not?
