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.

Example:
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;"
