"ulfheim" is an old domain name that I've had for decades; there's a little explanation on my home page but the short version is that it's from an old BBS handle.
Unfortunately a few years ago a racist hate group also started using the name for their own purposes. Today I've started the process of moving all my hosts to a new domain name, xargs.org .
