TXT records exceeding 255 characters
TXT RRs exceeding 255 characters are not allowed in infoblox. Some DKIM records are longer. Here's the workaround.
The workaround to adding a TXT RR longer than 255 characters in Infoblox is to split it in the middle and make it two RRs.
RFC 4408 (SPF) says this is OK.
Too long for Infoblox:
"v=DKIM1; k=rsa; p=MIIBIV-additional200-characters-here-nHyIpAv3XjhQUuyjz5283Hipwblargityblarg9i5QIDAQAB;"
This is OK -- note the additional quotes and space:
"v=DKIM1; k=rsa; p=MIIBIV-additional200-characters-here-nHy" "IpAv3XjhQUuyjz5283Hipwblargityblarg9i5QIDAQAB;"
