You could first call str_to_ip() and if it fails, call str_to_ip6(), and if that too fails then assume it's a FQDN. The str_to_ip() and str_to_ip6() functions are just wrappers for inet_pton(); they are declared in epan/addr_resolv.h.

Subject: [Wireshark-dev] Determine address type of string
Hello,
I am writing a custom dissector as a plugin. There I need to determine the address type of a string in a TLV. It can be either an IPv4 address, IPv6 address or a FQDN.
What is the best way to parse this string into the Wireshark data types?
My idea was to check which delimieters occur ("." -> IPv4, ":" ->
IPv6) iand if there dots, to check whether the parts between the dots are numerical.
Bye,
Jo
