Non existent domains in DNS

Postby MartynK » Sat Mar 19, 2016 2:49 pm

Am I understanding something wrong or what.

My server is getting hammered from domains ending in .xyz and .top each are valid 1st level domain names (as per wikipedia), but from what I can see they are not in use yet.

The are managed by the new domain company which does not list them as active and their whois reports them as invalid.

Something is resolving the domains in DNS as I can lookup a lot of the domains being reported in my logs, but they dont exist in whois.

Also the SMTP server on the end of their MX records is running postfix, but it will not accept a single command even to quit.

Anyone with any ideas ?
