against their primary NS ns1.linkedin.com

short TTL's on a lot of these domains

I just ran it again this time using Google name servers and still a lot of subdomains are pointing to the 214 server. confirmed it running against their NS, which means it hasn't been changed yet.

I've got my nameservice hardset through openDNS and it's resolving to, which is allocated to NASDAQ OMX according to ARIN...
