- How long can a DSN name in SBO be
I need to know how long DNS name i can use in Struxureware
The length of any one label is limited to between 1 and 63 octets. A full domain name is limited to 255 octets (including the separators
The clarification in rfc 2181 I think implies that the size of a fqdn (sent over the wire) is 255. There should not be any special SBO restrictions.
