It seems only the APN Network Identifier part ("internet" in your example) is mandatory whereas the APN Operator Identifier ("mnc012.mcc345.gprs") is optional. This behavior is defined in a spec known as "3GPP TS 23.003 Numbering, addressing and identification" [1]. Wikipedia provides a crash course for those who'd prefer to steer clear of Word documents [2].
