Abstract
Automatically the method for peer IP is obtained in a kind of local area network, it is related to field of computer technology, more particularly to a kind of method for obtaining peer IP in local area network automatically, it is the following steps are included: step 1: the server module of the device is run on the first host；Step 2: the MAC of other hosts is registered to the MAC list of the device server module, it is assumed that is MAC1；Step 3: repacking sets server-side and is sent to other hosts in local area network using broadcast technology；Step 4: the second host that the device client modules are run in local area network receives the broadcasting packet；Step 5: the client modules on the second host parse hardware address list MAC1 from message, if the MAC of this host is present in MAC1, will record the IP address and MAC Address of lower other side, if there is no then abandoning the message.After adopting the above technical scheme, the invention has the following beneficial effects: the host of user can obtain the new IP of other hosts in real time when other host ips change in local area network.
Description
Technical field
The present invention relates to field of computer technology, and in particular to obtains the side of peer IP in a kind of local area network automatically
Method.
Background technique
With the development of router and switch technology, more and more working teams can utilize in the same local area network
Main machine coordination working.One Team Member can not only operate the host of oneself, also can use the IP of other hosts in team
Address remotely operates other hosts, to increase working efficiency.
It is configured as in DHCP mode (dynamic host configuration protocol) local area network in a router or interchanger, one
Host is during operation or booting replay phase, IP may change.If an other host in local area network at this time
The host is remotely grasped, then will fail.Under normal circumstances, staff's peer of having to checks IP address, then
The login of oneself host remote is returned, the working efficiency and fluency of staff have been seriously affected.The present apparatus utilizes local area network
Interior broadcast technology is realized obtains peer dynamic IP (including during booting is restarted and run) in real time, to avoid above-mentioned feelings
Condition.Host IP address can be sent to the institute in the local area network by the device server module by LAN broadcast's technology in real time
There is host, if certain host has run the device client modules, will receive the IP address that other hosts are sent, at this time again
Distinguish which platform host is the IP address received belong to according to network device hardware address (MAC).
Such as application number: 201210413722.0, a kind of real-time device for obtaining server dynamic IP addressing, the mesh of the invention
Be it is real-time obtain client server dynamic IP addressing, reduce expense, the stability realized and maintainability.But through studying,
The technology can not be inexpensively conveniently suitable in the local area network of IP dynamic change.In the invention independent claims, " user client
End sign-on access proxy server can obtain the dynamic IP for the authorization server that it to be accessed in real time ": if staff thinks
The IP address of peer is obtained, then also needs to be separately configured the authorization server of a fixed IP.The situation will lead to work
The workload and expense for making personnel greatly increase, and in the local area network for dynamically distributing IP, can not configure a fixed IP
Server.These situations illustrate that the invention is not suitable for the local area network with dynamic IP allocation.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide obtain other side automatically in a kind of local area network
The method of host ip, it can reduce workload, reduce operating cost, when increasing working efficiency, when in local area network other
When host ip changes, the host of user can obtain the new IP of other hosts in real time.
To achieve the above object, the present invention is using following technical scheme: it the following steps are included:
Step 1: running the server module of the device on the first host, which, which is configured to be switched on, restarts and broadcast mould
Formula；
Step 2: expectation is received to the MAC(network device hardware address of other hosts of the host IP address) it is registered to the dress
Set the MAC list of server module, it is assumed that be MAC1；
Step 3: server-side is set in repacking can obtain host ip and MAC Address in real time, in addition MAC1, is sent to using broadcast technology
Other hosts in local area network；
Step 4: the second host that the device client modules are run in local area network receives the broadcasting packet；
Step 5: the client modules on the second host parse hardware address list MAC1 from message, if this host
MAC be present in MAC1, then will record the IP address and MAC Address of lower other side, if there is no the message is then abandoned, otherwise
Continue IP address and MAC Address that the first host is parsed from message；
Step 6: the second host is according to the MAC Address of the first host, to distinguish which host is the IP address received belong to.If
Host after changing for new host or IP address, then local data base is arrived in storage；
Step 7: staff searches its IP address from the database of the second host using the MAC Address of peer.
The host for running the device server module can be one or more host in same local area network.
After adopting the above technical scheme, reduction operating cost increases the invention has the following beneficial effects: it can reduce workload
When working efficiency, when other host ips change in local area network, the host of user can obtain other hosts in real time
New IP.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is the working principle of the invention flow diagram.
Specific embodiment
Referring to shown in Fig. 1, present embodiment the technical solution adopted is that: it the following steps are included:
Step 1: running the server module of the device on the first host, which, which is configured to be switched on, restarts and broadcast mould
Formula；
Step 2: expectation is received to the MAC(network device hardware address of other hosts of the host IP address) it is registered to the dress
Set the MAC list of server module, it is assumed that be MAC1；
Step 3: server-side is set in repacking can obtain host ip and MAC Address in real time, in addition MAC1, is sent to using broadcast technology
Other hosts in local area network；
Step 4: the second host that the device client modules are run in local area network receives the broadcasting packet；
Step 5: the client modules on the second host parse hardware address list MAC1 from message, if this host
MAC be present in MAC1, then will record the IP address and MAC Address of lower other side, if there is no the message is then abandoned, otherwise
Continue IP address and MAC Address that the first host is parsed from message；
Step 6: the second host is according to the MAC Address of the first host, to distinguish which host is the IP address received belong to.If
Host after changing for new host or IP address, then local data base is arrived in storage；
Step 7: staff searches its IP address from the database of the second host using the MAC Address of peer.
The key point of the present apparatus be allow device booting to restart and the IP address of real-time broadcast oneself, and client can
With MAC Address list in message whether containing oneself MAC Address, if information in remaining packet will not be parsed without if, to reach
To the case where preventing IP address information to be exposed to other hosts.
The above is only used to illustrate the technical scheme of the present invention and not to limit it, and those of ordinary skill in the art are to this hair
The other modifications or equivalent replacement that bright technical solution is made, as long as it does not depart from the spirit and scope of the technical scheme of the present invention,
It is intended to be within the scope of the claims of the invention.
