Comment # 3 on bug 11513 from 
Thanks for your explanation. I find a NAS dissecotr to dissect below NAS ASN.1
encoding data. It shows Protocol Identifier as "Unknown Protocol (0x03)"
whereas wireshark NAS dissector shows the corresponding Protocol or Container
ID as "DNS Server IPv6 Address (0x0003)". I am not familiar with NAS protocol,
I will check the 3gpp document.

NAS ASN.1 encoding data:
270000000001074201FF064064F020000100295263C1090958584040000000000B037765620374696D02697405012B88CC4A2708810003046E03570E500BF664F020000101AABB04374A09217389216389215389340A030911F2050C29345576640103

critical part of dissect result:
PDN Address := {
                PDN Type = IPV4 (0x01)
                Internet Protocol V4 =  43.136.204.74
                Internet Protocol V6 =  0:0:0:0:0:0:0:0
            }
            Protocol Configuration Options := {
                Configuration Protocol = PPP (length: 1)
                Protocol Identifier = Unknown Protocol (0x03)
                Protocol-ID Contents = (length: 4)
                    0x6E 0x03 0x57 0x0E 
            }
