I performed an SOA nslookup on a domain and I am little confused by the exact meaning of the output (see below...names have been changed to protect the innocent):
;; QUESTION SECTION: ;MYDOMAIN.COM. IN SRV ;; AUTHORITY SECTION: MYDOMAIN.COM. 10800 IN SOA dns23429.dizinc.COM. somename.hotmail.COM. 2010072201 86400 7200 3600000 86400
So I understand that "dns23429.dizinc.com" is the authoritative DNS server but what is the meaning of the entry after that ("somename.hotmail.COM")? Is that another authoritative DNS server? I didn't think you could have two authoritative servers. In addition, why would it be on a machine at in the "hotmail.com" domain? That seems kind of strange doesn't it?
