Strange....
Assume your device is 192.168.1.3 (LiteonTe_[last bit of ethernet address overwritten!] )... but not giving the full picture makes it hard.
nslookups on these gives,
31.62.64.1 public-gprs301248.centertel.pl.
31.62.98.40 public-gprs309991.centertel.pl.
whois gives...

So it's "Polish Orange". I'd say it's more likely that you are using a peer to peer network &/or a VPN and that it's "leaking" arps.
Or could a phone on the network or any of a number of other things, like the provider network leaking an arp -
JuniperN is likely JuniperNetworks so that could be your provider's router (depends what the topology is) leaking to your side.
Or it could be even a case of possible Arp cache poisoning. Anything is possible with M$hit & Windoze.
