linux – Why am I getting “has address” not responding for only one site

It’s been a few days since I cannot resolve on my laptop.

I don’t seem to have any problem with other URLs.

host has address has IPv6 address :: mail is handled by 10

When I ping it seems that my computer think that it’s localhost.

On other computers in my local network it works perfectly fine so it doesn’t seem to be a problem with my ISP modem router DNS.

host has address has IPv6 address 2a00:fb40:a:1::140 mail is handled by 10

I tryed to clean the dns cache with /etc/init.d/dns-clean restart but it doesn’t change anything. My /etc/hosts file seems OK, my /etc/resolv.conf is the same as one from a computer without the problem.

I am not an expert in network stuff and I don’t know what to do about this.

Has anyone an idea to solve this ?
