In out of box instances, domain.name has a max limit of 40 characters and domain Path has a 255 character max lengthThe domain tree supports 216,000 child domains with 63 levels within each domain Domain Path max length of 255 characters is just enough to support the maximum number of domains records and levels permitted within the instanceAs a result, if the underlying MaxLength values for domain.name or domain.domain_path fields are modified to either increase or truncate (truncating is never recommended anyways), there is no telling if the domain_paths can be calculated accurately by the system. Conclusion: ServiceNow does NOT recommend making any changes to the Max Length of domain.name and domain.domain_path fields Applicable Versions All releases Additional Information https://docs.servicenow.com/csh?topicname=r_AdministerServiceNow.html&version=latest
