I had a public site some time ago with two registered domains: www(dot)subnetskills(dot)com, and www(dot)subnetskillz(dot)com. In January, I allowed the registration on the domains to expire, and shut the sites down. As it happens, I kept the public IP, and I have a Dyndns domain name pointing back to it for personal stuff.
A few weeks ago, I noticed I could no longer access my pages on this site from my AT&T phone, or from my desktop at work. The security team called and said they found a problem, but that it's no big deal from their perspective, and that it looked like someone hijacked my IP. After a bit of digging, it looks like ww2(dot)subnetskillz(dot)com and/or www(dot)subnetskillz(dot)com may be referring to it, but it's hard to tell; I'm not exactly sure what I'm looking at. If I look up the whois, there is little useful information. If I try going to the URL, I get a parking page. If I go to http(colon)//www(dot)sitedossier(dot)com/site/www(dot)subnetskillz(dot)com, I see that it refers to my public IP.
Anyone know what might be the issue, or more importantly, how I might get this corrected?
As sjr2004 said, I allowed the domains to expire (in January - about 11 months ago). The static public IP address I have, however, is the same as when the domains were active. I've had it since January 2011.
I really don't care that someone took the domain name. The concern is that 1) they are somehow linked to my IP address, and 2) are identified by a number of services as hacker or otherwise 'bad' sites. As a result, when I try to connect to my site using my dyndns FQDN, I can't connect because proxies at my company, AT&T wireless, and likely others are blocking *my* reputable pages.
@ derp: Public IP = routable IP address (i.e., not 192.168.x.x, 172.16.x.x, or 10.x.x.x). In this case, my public IP is also static - it's the same IP address I got when I opened my account with my ISP in January 2011.
Don't think webhosting provider - my IP terminates at my residence, so I own/operate my entire infrastructure (servers, firewalls, networking, etc.)
