derext.com shares its name server setup with other domains, including lenz-electric.com, 3retrievers.com, spgatewin.com and two others.
derext.com has at least partial name server overlap with other domains, such as theoliverandco.com, cottonwoodsilks.com, baumhardts.com and two others.

adns.cs.siteprotect.com directs to 64.41.112.12 and bdns.cs.siteprotect.com directs to 64.41.114.12; each host name points to exactly one IP number.
