A typical SPF HELO policy v=spf1 a mx ip4:192.0.2.0 -all may execute four or more DNS queries: (1) TXT record (SPF type was obsoleted by RFC 7208), (2) A or AAAA for mechanism a, (3) MX record and (4+) A or AAAA for each MX name, for mechanism mx. Except the first one, all those queries count towards the limit of 10.

Computed as unix time ⁄ (60×60×24) mod 2 10, it can be stored as a two base32 characters, with a recycling period of about 3.5 years. The hash-based message authentication code ( HHH ) is computed against a local secret, but only a part of it is used; for example, storing the first 4 characters of a base64 representation provides 24 bits of ...
In the Domain Name System, a LOC record (experimental RFC 1876) [1] is a means for expressing geographic location information for a domain name. It contains WGS84 Latitude , Longitude and Altitude ( ellipsoidal height ) information together with host/ subnet physical size and location accuracy.
