If an IP address is defined based on InetAddressType/InetAddress TC, then the OctetString in byte format (aka C0:A8:01:23) is the correct return for an IPv4 address. I believe that most - if not all - Cisco's routers and switches use InetAddress to express the IP addresses.
For the case of 192.168.1.34, you may want to check the corresponding MIB definition of that object. If that's an InetAddress object, then IMHO returning "xxx.xxx.xxx.xxx" is an incorrect development. If it's a DisplayString/SnmpAdminString object, then it's a different story.
