The CIDR address we specified indicates that the first 23 bits are used for the network block we are referencing. This is equivalent to a netmask of 255.255.254.0, or: 1111 1111 - 1111 1111 - 1111 1110 - 0000 0000
The maximum number of DNS lookups for the SPF record is 10. If you are using IPv6 IP addresses, replace âip4â with âip6â in the previous examples. You can also specify IP address ranges using CIDR notation, for example âip4:192.168.0.1/26â.hen you set up your service, you created an SPF record in your DNS provider records that identifies the Microsoft messaging servers as a legitimate source of mail for your domain.
