I have never liked iPhone, arcade, and it's so expensive. But two galaxy mobile phones have been changed in February this year, and Nokia has been used for the past N years. This time, I have a deep understanding of the Black iPhone. The iPhone

1. What is SPF?Abbreviation for sender Policy Framework, a technology that authenticates e-mail senders as IP addresses, is a highly efficient spam solution.The receiving party first checks the domain's SPF record to determine if the sender's IP address is included in the SPF record, and if it is considered to be a correct message, it will be considered a forged message to be returned.2. How do I set SPF for my mailbox?(1). SPF is implemented with the TXT record setting for the domain name.To im

IP address acquisition and conversion, IP address acquisition and conversionIP address acquisition and conversion 1. Preface Converting an IP address to an integer storage is a major trend in database optimization. String indexes consume a lot of resources than integer indexes, especially when the data volume in a table is large, and query the data of an ip segment. The IP address mentioned in this article is ip4, and ip6 is no longer in scope 2.

to work properly. In this case, the display usually has a prom memory that stores the display parameters. This is very convenient, but the prom also occupies a relatively large memory space.after reading the above paragraph, someone should understand. In fact, this is only two ways, it is the mobile phone processor data transmitted to the LCD, and displayed, the results are the same. As Meizu engineers have said, the current processor is fully capable of handling ram at once. Here are some of t

) SDP Syntax: SDP is also described in text format. An SDP description can contain many rows. The format of each row is as follows:Type = ValueType is represented by only one letter. An SDP description usually consists of a session-level and multiple media-level information. Session-level information is used to describe the entire session, each media-level information is used to describe a specific media stream. Session-level starts with "V = 0" and media-level starts with "M = V = 0O = Bob 2890

SPF is a DNS record type proposed to prevent spam. It is a TXT record
