[tech] UCC SPF\DKIM records

[Steven Lim]

Hi James et al

We're just reviewing DNS records related to SPF\DKIM. We note that the UCC have some records in place and we're after additional information. The records in question are as follows:

Domain			Type	Usage	Record					Value
Ucc.asn.au		TXT	DKIM	ucc-2016-3._domainkey.ucc.asn.au.	v=DKIM1; k=rsa; t=y; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC5fGQBeHII4Slf0iIguwwuLcbWmHv0JaNyUgubDIevYXpaZQdd5WrBO8sQcTezxbKlovMQFK1T5S1Z4tToWr7+Q6w3enVHkAFyT6qYSONzi4pcK3HKhG2DHwIaFm6csyjDQg0tk7dHgAqdjgQitPn84dbrbAGjJ24mxipdDNsoVQIDAQAB

Ucc.gu.uwa.edu.au	TXT	DKIM	ucc-2016-3._domainkey.ucc.gu.uwa.edu.au.	v=DKIM1; k=rsa; t=y; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC5fGQBeHII4Slf0iIguwwuLcbWmHv0JaNyUgubDIevYXpaZQdd5WrBO8sQcTezxbKlovMQFK1T5S1Z4tToWr7+Q6w3enVHkAFyT6qYSONzi4pcK3HKhG2DHwIaFm6csyjDQg0tk7dHgAqdjgQitPn84dbrbAGjJ24mxipdDNsoVQIDAQAB

Ucc.guild.uwa.edu.au	TXT	DKIM	ucc-2016-3._domainkey.guild.uwa.edu.au.	v=DKIM1; k=rsa; t=y; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC5fGQBeHII4Slf0iIguwwuLcbWmHv0JaNyUgubDIevYXpaZQdd5WrBO8sQcTezxbKlovMQFK1T5S1Z4tToWr7+Q6w3enVHkAFyT6qYSONzi4pcK3HKhG2DHwIaFm6csyjDQg0tk7dHgAqdjgQitPn84dbrbAGjJ24mxipdDNsoVQIDAQAB

Each of the domains also has the following SPF record:

v=spf1 ip4:203.27.114.0/23 ip4:130.95.0.0/16 ip4:139.138.31.0/24 ip4:139.138.42.0/24 include:spf.smtp-engine.com include:spf.forwardemail.net ~all

Could you please advise:
1. What is the DKIM record ucc-2016-3._domainkey used for? Is it still required?
2. What are the following SPF records required for and are they still required?
	a. ip4:203.27.114.0/23, appears to be your entire network
	b. ip4:130.95.0.0/16, the entire UWA network
	c. ip4:139.138.31.0/24 ip4:139.138.42.0/24 UWA IronPorts, soon to be phased out. The first record has already been decommissioned
	d. include:spf.smtp-engine.com, Unknown

If you could get back to me asap.
