Just for the heck of it, try pinging with different packet sizes, e.g.:
ping -s 1024 8.8.8.8 ping -s 576 8.8.8.8
ping -s 1024 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 1024(1052) bytes of data. 72 bytes from 8.8.8.8: icmp_req=1 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=2 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=3 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=4 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=5 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=6 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=7 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=8 ttl=48 (truncated) ^C --- 8.8.8.8 ping statistics --- 8 packets transmitted, 8 received, 0% packet loss, time 7009ms rtt min/avg/max/mdev = 45.515/46.895/51.445/1.761 ms [mb@mbv ~]$ ping -s 576 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 576(604) bytes of data. 72 bytes from 8.8.8.8: icmp_req=1 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=2 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=3 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=4 ttl=48 (truncated) 72 bytes from 8.8.8.8: icmp_req=5 ttl=48 (truncated) ^C --- 8.8.8.8 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4005ms rtt min/avg/max/mdev = 41.736/42.320/42.977/0.529 ms [mb@mbv ~]$ ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_req=1 ttl=48 time=38.3 ms 64 bytes from 8.8.8.8: icmp_req=2 ttl=48 time=37.3 ms 64 bytes from 8.8.8.8: icmp_req=3 ttl=48 time=37.7 ms 64 bytes from 8.8.8.8: icmp_req=4 ttl=48 time=37.5 ms 64 bytes from 8.8.8.8: icmp_req=5 ttl=48 time=37.7 ms ^C --- 8.8.8.8 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4005ms rtt min/avg/max/mdev = 37.320/37.730/38.325/0.413 ms
That's right, thanks.
