Multiple PTR records are used, for example, when a web server supports many virtual hosts— i.e. multiple hostnames then resolve to a single address, and multiple hostnames will be returned for a PTR lookup for that shared address. However, DNS lookups typically occur over UDP, and since UDP has a limited message size, in extreme cases, multiple PTRs could cause a DNS response to exceed those UDP limits. --- $ host 180.250.59.246 246.59.250.180.in-addr.arpa domain name pointer mail.ciputrahospital.com. 246.59.250.180.in-addr.arpa domain name pointer mail.ciputra.co.id.
