TCP/IP Stack, DHCP Client fails with FQHN longer than 25 chars

Hello Keil users

We are using PK166 and the TCP/IP stack of the Advanced Realtime Library AR166.

An embedded application has to use the fully qualified host names (FQHN) to be identified correctly in an large local area network.

Our application works fine with fully qualified host names up to 25 chars ("abcdefgh.test.example.org")

With longer names the DHCP session is stoped by error (malformed frame DHCP REQUEST from embedded client to the DHCP server).

Is this a limitation of the stack or a bug?

Best regards
Christian
