16进制代码转换

Question

iptables -A FWSNORT_INPUT -p udp --sport 53 -m string --hex-string "|81800001000100000000|"  --algo bm -m comment --comment "sid:254; msgNS SPOOF query response with TTL of 1 min. and no authority; classtype:bad-unknown; rev:4; FWS:1.1;" -j LOG --log-ip-options --log-prefix "[94] SID254 "

请问--hex-string "|81800001000100000000|"  这里面的16进制代码是什么，怎么看哦
