ping -v is now deprecated which was useful for sending ICMP with TOS field values. Try ping -Q as alternative from a UNIX machine.
-Q tos Set Quality of Service -related bits in ICMP datagrams. tos can be
either decimal or hex number. Traditionally (RFC1349), these have
been interpreted as: 0 for reserved (currently being redefined as
congestion control), 1-4 for Type of Service and 5-7 for Prece-
dence. Possible settings for Type of Service are: minimal cost:
0x02, reliability: 0x04, throughput: 0x08, low delay: 0x10. Multi-
ple TOS bits should not be set simultaneously. Possible settings
for special Precedence range from priority (0x20) to net control
(0xe0). You must be root (CAP_NET_ADMIN capability) to use Criti-
cal or higher precedence value. You cannot set bit 0x01 (reserved)
unless ECN has been enabled in the kernel. In RFC2474, these
fields has been redefined as 8-bit Differentiated Services (DS),
consisting of: bits 0-1 of separate data (ECN will be used, here),
and bits 2-7 of Differentiated Services Codepoint (DSCP).
Man curl or curl –help
Curl can be useful to check TCP connections for http or https.
Result could be Connection Timeout, Connection Refused or Connected (200 OK).
